X1 Remote Wish List Mark 1

There are probably a multitude of items on every user's wish list, but I'm hoping that my wishes come true.
Wish 1. The handset constantly has a delay or hangs. When and how can the delays and hang-ups be eliminated?
Wish 2. Identification of actions on the handset. With multiple devices in the activity it is essential that actions are easily identified for the device it controls. For example, I have arrow left and right on 2 devices but have no idea which one does what on the remote. Can the actions be grouped or colour coded?
Wish 3. Order of key favourites set-up in the app should be mirrored on the handset, but they seem to be random. Can they be grouped?
Wish 4. It should be a basic function to be able to; add, delete and sort device actions in the app and have them repeated, in the same order on the remote. I don't want to rebuild the keys every time a change is needed, what and when can this basic function be incorporated?
