WebExtension

Should return the path of the RC file sourced, since phantom RC files seem to trip users up every now and then

I'm generally very satisfied with the extension, but sometimes you find the websites that are not supported. Recently, me and my friend had some problem with setuping Discord to listen to music together, so we moved to the first Google result.

https://sync-tube.de/

the general idea is very simple. After joining the room, everyone can search for the videos and play them in embed player, which

• Linux
• Windows
• Firefox

Linux is pretty similar and even easier than macOS, there is a google-chrome binary in PATH and it can be parsed to any of the channels. (google-chrome --version)

Small UX improvement idea:

Companion should keep track of errored loads from local gateway and attempt to reload respective tabs (if still present) when API state changes from offline to online.

Should be able to add known app match patterns to the whitelist via a dropdown (or similar) method.

⚬ PROBLEM:

Some content creators make videos where the aspect ratio changes during the video. When their video itself has a different aspect ratio than the monitor of the viewer, the "transparent background" option creates two differently colored bars, which is distracting in my opinion.

Is your feature request related to a problem? Please describe.

I find that the extension has a significant impact on my eyes when setting grey/whitelists. I could not find any other issue related to this, so I thought it could be something to be considered.

Describe the solution you'd like

Implement a inverted or dark color scheme for the extension UI.
