Small side question. Can You give any approximation - how difficult it is to enable subtitles on as default?
Ref: Subtitles, on as default
I suspect that you mean a systemwide setting for subtitles, so you don't have to manually activate subtitles on every single channel?
No idea how long creating such a setting would take, sorry.
I suspect that you would have to edit the python parts to get it done though.
