All the images are downloaded and cached eventually, but I have no idea if there are still more to download. For example, what about fan art?

The custom http queries button I have planned for the bottom menu bar. I have finished the top menu bar as you can see a few posts back...next on my list is the bottom menu bar. The new bottom menu bar will also be scrollable (left and right). If you want to you can place every available button on it (including the ones you see in the remote).
I was also thinking of the ability to assign Kodi commands to a button, so you won't have to go through the commands menu.

I can make a setting that when you start a movie (episode, or whatever) you go automatically to the remote control.

My first priority is the bottom menu bar and next the Music view.
