intro-skipper project dead?

[nothingveryobvious]

I noticed the plugin has the option "Enable injected server-side skip." Should I check the box? I don't understand what it does.

I currently use Jellyfin via:
- Roku
- Android TV
- Kodi

I know that for now, the skip buttons aren't available for those clients. So do I have to check that box in order to allow auto-skip? Or if those clients had buttons anyway, do I still need to check that box?

Basically, what does it do? lol

Thanks!
