Missing episodes & uncommon extensions

Hi dear TMM team,

i would like to suggest 2 features:
1. Adding uncommon extensions. I use an enigma2 receiver, which adds some files to every recording, containing all informations like the xml files of kodi do. It would be great, if i could add this extensions (ap, cuts, sc……) as additional extensions to be renamed/moved and kept with the original movie-file without treating them as audio/video or subtitle file

2. When a season is selected, all the available episodes on disc are shown on the right panel. It would be great to see the missing episodes in an another color too. With copy&paste abillity, it would be possible to add this missing episode name to tv-browser, or other tools to get them recorded

Keep the great work
Greetings
