I have added custom playlist support (random and recent) for all home screen custom categories.

Please try out the development version of Rapier to test it out. And report back what you think

Awesome, it works perfectly!

I also couldn't find a way to show covers/thumbs in the "widgets" (next episodes, recent movies), at least on hover. Widgets are quite minimal.

That's part of the design.
Posters or thumbs are shown by default.  

Oh, I actually didn't notice those at first, because they are very small, barely readable. So maybe I'd appreciate them to be a bit larger, or have a poster-only list.
It may also be handy to add some useful info on selection, like when the video will finish, if selected (Something like "Ends at: 00:00" below the image).

For TV Series and Anime (my playlists) I see thumbnails only for some of the items, for some I get:
XFILE::CDirectoryFactory::Create - unsupported protocol(image) in image://http%3a%2f%2f192.168.1.100%3a8096%2femby%2fItems%2f885cef3829695dbd25e896858a868947%2fImages%2fPrimary%2f0%3fFormat%3doriginal%26Tag%3dde8003c3c6026aeebf0938f3b5e209aa/

Oh and the few thumbnails I see are stretched

Skin settings > Media > Fullscreen video > Show clear art on OSD (falls back to clear logo if no clear art is available).

Interesting, I had that set already, but I still don't see clear art on OSD.
Again, I'm using Emby and that could be related to the problem, but I see the clear logo in the Wrap Info view.

Thank you again, the random background for playlists made my day.
