It would be nice to be able to watch TV without needing to enter password ;)
Additionally, I would like it to use bluetooth for audio. I read somewhere that Kodi 18 has some improvements regarding bluetooth, and I could install that from a PPA. If I run Kodi from a desktop environment I can connect bluetooth device using graphical tools i.e. blueman-applet and pavucontrol (to control Pulseaudio), but I can not use them when I run Kodi from the login screen as standalone app if I may say so.
