The next version will have a fix for one of the image options, hopefully that helps.

You can disable autoplaying media in the native Reddit settings:
Settings > Preferences > Autoplay media

Thanks for the review, I'm glad you find it useful!

Edit: We've just released version 2.0.1 with a lot of bug fixes and improvements. I'm glad it works better now :)

Interesting, sorry about that. Are you using any of the default sort option features, or enabled any new options since the update?

Reddit might be testing a new build of the site for some users and broke the feature. It still works fine for me at the moment, but I will keep an eye on it and see what I can do.

Thanks!

I'm not sure if I will be able to access the Reddit API to mute communities officially, but I can add a filter to block/hide posts from a certain subreddit on feeds set in the extension.

Amazing review haha, thanks! :D I'm glad your retinas aren't burning anymore!

Regarding your points:

1) I'll add a new style option in a future update for the profile page comment background colour.

2) Unfortunately, I can't make the popup stay open, but I have a few options you can try:

a) I added a "shade" button at the top right of the popup window. This will "minimise" the popup so you can see underneath, but if you click outside, it will close.

b) Perhaps a better way, you can click the "Options Page" button to open the options in a new tab. You could then drag and detach the tab and put it on a second monitor, or resize it and switch between it and your main browser window, or just keep it as a tab.

c) Bonus option. Go to "about:config" (in the URL bar) and search for "ui.popup.disable_autohide" and toggle it to "true". This will keep the popup permanently open, but you can't close it unless you toggle the option back to "false". You could combine this with the shade option!

3) I'm afraid not, I can't access user local storage for security reasons. However, it is possible to convert images to base64 code, then that code can be stored safely in the extension local storage in the browser. I think the maximum an extension can store locally is 10MB, so you'd have to use a small image or reduce the file size. Browser sync storage is only 100KB, so syncing images is out of the question. I could automate this process and you simply just upload an image, but you won't be any to store many.
