Works but cumbersome stations handling ohen favorites list

This eternal gescrolle annoying to get to the appropriate channels.
On PC via browser you can create a Favorite at Zattoo.com list. Here in the App nil.
Prefer not constantly have to zap through 10x WDR regional programs, or by other unimportant for me sender.
Too bad that has done nothing in this direction since September. I mean for 100 in may well expect an intuitive operation. A neat, self-customizable favorites list would be asking too much. Hope you get another station added.
Further, the image is often stand. after 10sec. then you continue. A buffer problem on FireTv? Who knows.
So please Zatto team. Take the app nevertheless times to chest!
