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.

This is Reddit forcing users onto the latest version. I'm surprised your work around worked tbh, but I guess it won't last :/

I'm afraid this is Reddit forcing users onto the latest version and it conflicts with the extension. Nothing I can do about it, sorry. You'll have to disable the redirect feature, or choose the Old UI.

Hi. The option is called "Show Navigation Buttons For The Next/Previous Root Comment" in "Productivity", or search for "root". This option, however, is only available for the latest and "old new" versions of reddit. I'll try and add support for old reddit.

Hi. These settings should work. If refreshing your browser doesn't help, please report the issue on GitHub, along with browser and extension versions and I'll try to help figure out what's wrong.

This is odd, I've not come across this behaviour before. How often does this happen? If you could report this issue on GitHub and let me know which settings you have enabled, that would help. Thanks.

You're welcome, I'm glad the extension has helped :)

Thanks for the great review! RES was the OG, I wanted to fill the void for the newer versions of Reddit. I'm happy you enjoy the extension and find it powerful :)

What doesn't work? If you are referring to the redirection to "Old New UI", Reddit is discontinuing this version and users will eventually loose access to it. There is nothing I can do about it unfortunately.

Thanks for the review! :)

Hi. Yeah it seems Reddit is phasing out new.reddit unfortunately :/
I'm happy you like the modernised version of old.reddit, I'll revisit it soon with some more improvements. I can start adding more style options for old reddit so you can pick whatever colours you want.
Thanks for the review! :)

You need to be signed into Reddit unfortunately for it to redirect to the Old New UI, otherwise Reddit will force a redirect to the latest version, causing this error, as it conflicts with the addon redirect function.

Edit: It seems that Reddit has now broken, or disabled, new.reddit.com for some users. Other redirect extensions are having a similar issue apparently. I'm not sure if this is something Reddit will fix, or if they are doing it deliberately to force users onto the latest version :/
