NEW VERSION AVAILABLE:

https://steemit.com/steemdev/@armandocat/steemit-more-info-1-4-chrome-extension-firefox-extension

A simple Steemit extension that shows more info on steemit.com

If you use steemit.com, you may have notice that it is lacking a lot of functionalities.
That's why you need to use tools like https://steemd.com/, https://steemdb.com/, https://steemstats.com/, https://www.steemnow.com/, ...
A lot of tools!

So why another tool???
Because this is a Chrome and Firefox extension that you install on your browser, and then all the informations you need will be available to you directly on steemit.com!

Please take into consideration that this is a new project that I just started, and the features are limited to just a few so far! I'm planning to add more and more features in the next versions. Every suggestion and idea is very much appreciated!

This is version 1.3 with some bug fixes and a few features added

Features

In the profile page of any account, you will see a Vote Power indicator on top (next to the name and the reputation), with the reward that a 100% vote from that user will give in SBD ($)
In the profile page of any account, you will see the number of votes that user has done today

A new tab 'Votes' is added, where you may see the latest upvotes done or received by that user.
It shows the estimate of the votes in $ too!
You can filter the votes between incoming votes and outgoing votes

Added a dropdown menu with links to external tools to get more info about the steem account. Please let me know what tools you'd like to see here ;)

When you click upvote and the Vote Weight slider appears, not only you see the percentage of the vote, but you also see the amount in $ that upvote will be valued

For downvotes, it shows also the total reward of the post after your downvote

When you are looking at a post or comment and you click "votes" to see the list of people that voted that post, you now also see what was their contribute to the total reward!

You can see the posts with two different layouts: list (default) and grid! You can change to grid layout using on the buttons on the top-right corner of the page.

On the blog page of an user, you now see an histogram of the posts of that user based on the creation date. You can scroll horizontally to go back in time.
Posts made by the user are shown in blue, reposts in green!

By clicking on one of the bars, you can open the list of posts made on one specific date. This makes it easier to look at old posts of an user!

You can choose to show the histogram automatically on page load (default) or if you prefer to load the histogram on request if you find it to be too invasive. To change this setting, hover on the histogram title and select "On load: hidden"

The followers and following pages have been updated to show a table of the followers/following, with more informations (Reputation, STEEM Power, Upvote Worth). You can sort by the different attributes by clicking on the table's column.

When you read a post, now there is a floating bar with the tags, date, author and upvotes of the post, so you can easily access this informations and upvote the post if you like it!

If you prefer a less intrusive way, in the setting you can choose the small floating bar layout

The markdown editor used to write new posts now shows the preview at the right side of the editor. While you write the post, if you scroll through your textual content, the preview will automatically scroll to the right point. This feature is available for screens with at least 900px width

If you want to better see the avatar of an account, just hover on the user picture to open a bigger version of the avatar image

GIF Picker for your posts and comments! You can search by keywords or see the trending gifs of the moment. Powered by Giphy

Boost your posts easily with the Boost button next to the "Promote" button. You will be able to easily transfer SBD to @minnowbooster for an upvote of the whale!

You will be prompted with a confirmation form where you will see the estimated worth of the upvote you will receive. No more copy and paste of the url in the memo field of the transfer and risks of sending a wrong transaction

Special thanks to @reggaemuffin and the @minnowbooster team for the support in making this feature possible!
Version 1.3 had a bug in the generation of the memo to be used in the transaction. Please update to version 1.3.2

Steemit More Info Settings. You can now choose to enable or disable each of the features provided by Steemit More Info! Just go in your account settings.

Future development

I'm planning to add more features like:

COMING SOON: Trending of up to 5 favorite tags in one page. You select your favorite tags and you'll see the list of the top trending of all the tags combined in one list. I'm not releasing this feature yet because it still has some bugs.
Notifications, for instance if somebody replies on one of your posts or comments, if you get an upvote, ...
A page with some graphs of the stats of the account
...

Privacy and security - Do I steal your data?

I do not access your private keys. The only way I could do it, is if you go to your wallet page and click on "show private key". But I don't do it!
Should you trust me? Well, I believe is better not to trust anyone. That's why the source code of the extension is available on github and you can (and you are encourage to) look and study it!

The way it works is by scraping the webpage and the url of the page you are looking at to extract your username and the username of the user you are looking at. Then it uses steem-js to get informations about that user.
This process doesn't involve any private key! In fact, you can see informations of other users as well, even if you obbiuvsly don't know their private keys.

Code audit

@reggaemuffin made a full code audit of this version of the extension looking for bugs or security problems.
Here's a summary of his review:

There was a possible issue with the way the presence of a new update was checked that could have allowed if @armandocat github account were compromised to inject a string into the html page. However, the code would not have been executed so no malware could have been injected in the page. Code has been updated and now use a normal ajax call

/vendor/* contains javascript files unchanged from the last release of the libraries used

src/post_boost_button.js is doing ajax requests to the minnowbooster api and these submit the author and permlink of the post you are viewing and your username to minnowbooster.net (to check your minnowbooster limits for your convenience). This happens only when you click on the "boost" button, so if you prefer not to send this information to minnowbooster just disable the feature and don't click on the "boost" button.

src/markdown_editor_beautifier.js will load a few iframes in your markdown editor if you include them. Iframes are sanetized before being embedded. Still this is to be kept in mind. Images are loaded automatically and are checked, but you can probably hack yourself by adding an image tag that links to a malicious script. Link tags are opened in a new tab and have noopener set, which prevents a security issue: https://mathiasbynens.github.io/rel-noopener/

src/gif_picker.js: found a few cases where rel-noopener was not applied and these were fixed before release to the users. This will call the giphy.com api and search for gifs.

src/followers_table.js will call img.busy.org to retrieve profile images.

src/external_links_menu.js: all external links were subject to rel-noopener. Fixed in this version

src/utils/utils.js: this is doing all the heavy work and has the strongest focus in this review. All methods that interact with the blockchain are read only and safe.

The bugs expressed have already been fixed prior to the release of this version.

Thanks to @reggaemuffin for his effort in checking the code for potential vulnerabilities. He will confirm shortly this analysis by commenting on this post.
Please consider adding @reggaemuffin to your witnesses list!
