Good idea ! I will have to think on this implementation. It was too short to do more on that first public release, till one year of programming :) But for sure, new functions can be added, I always take users feedback and implement if I think interresting !
as far I can see teletext is only used for subtitles or did I missed something? how to use full teletext? If not possible maybe you could add this feature maybe new tab or as TV split screen? thank you
