Visual indication when new video is added/re-added
I originally had #277 (closed) and I have to admit I've tried that "add video URL" before, but I thought it did not work, because nothing changed.
So when I added https://daserstehdde-lh.akamaihd.net/i/daserstehd_de@629196/index_3776_av-p.m3u8 I guess it was already added, and so it did not do anything.
What happens
Nothing.
What should happen
Highlight the existing video/scroll to it/show a small red blur around it etc.
