Dynamically adapt theme to system preference

[Mynacol]

Is your feature request related to a usage problem (not a bug)? Please describe.
Most of the applications on my (Linux) system can switch between a light and dark theme. FreeTube bugs me, as it doesn't change the theme if I toggle the system-wide theme.

Describe the solution you'd like to see implemented
FreeTube should add a theme option, System, which selects a light theme if the system-wide theme is a light one and a dark theme (if dark or black could be another option) if the system has a dark theme.
This should ideally work during usage, so no restart is required to "automatically" change the theme.

Describe alternatives you've considered
I see no way to change the theme with a command line tool.
Editing theme in settings.db in the configuration directory seems to change nothing.

Screenshots
(No screenshots by me)

Additional context
I think this is the related electron manual.

I hope it'll be implemented. Same applies to macOS and Windows.

Agreed! Switching based on system theme would be awesome.

I'd also appreciate this feature being added. If it would follow the system theme and change to the light theme or the dark theme automatically based on what the system theme is, it would improve the integration with the system, and it would be a welcome change for me. Thanks for all the work you've put into this wonderful app!

I'll try to work on this tonight/tomorrow, afaik it should be a fairly simple change with a new theme preference. I don't think anyone else started work on this? Let me know.

U can work on this. Nobody started to work on this.

Quick update on this: trying to debug an issue with nativeTheme not passing down the OS preference dynamically with some electron folk. Looks like it might be a linux specific issue but I'd like to get it sorted before making a PR. Otherwise everything is pretty much sorted :)

I'd like to see this one on MacOS too!

Additionally, You can add light/dark mode theme option, allowing users to choose built in themes for light/dark mode.
