Let me start by saying, that I really like the SRL App and the issues I have are only very minor annoyances, but maybe some of them are quick and easy to fix.
The text of video titles is often cut off, even for very short titles. (Solution here could be to reduce the font size a bit and allow the title to be displayed in more than one line ore make the text scroll when hovering over it).
While playing a Video I would like to have a Preview Picture while hovering over the timeline like in the Webrowser-Version.
The ability to see created Playlists from other users.
Let me look at my History in the App.
Let me see the upcoming Videos. (Probably not possible, but a short trailer for upcoming Scenes would be nice in general, or even only short scene description + participating Pornstars)
