Is there a jump bar?

Been testing out playing back my own media in Channels and one thing that is missing is an 'A to Z' jump bar. (Unless it's there and I don't know how to turn it on? Using a Nvidia Shield as a playback device.)

I have lots and lots of movies and being able to just select 'M' to pop me into movies that start with that letter would be nice.

Also, after I had scrolled through a few hundred movies, I couldn't find a way to get back to the top and select; 'recently added', 'alphabetical' etc. Having some sort of shortcut to get back up there quickly would be another good feature.

On a super positive note, I LOVED being able to see a thumbnail of where I was when fast forwarding through a video.

PS Where does Channels cache information about your personally added media files? In Plex, my library eats up about 30+ gigs of cached information. Just curious where Channels stores that so I can compare.

Would also like to see something like this ...
