Like for example if if im driving around, and i might want to use a ui app, lets say the replay one, instead of going into the ui apps selector each time, i can just click on unminimize, and it will pop up, and when I'm done i can just click minimize, and it wont clutter up my screen, and save time by not needing to go and pick it from the ui app selector, and then removing it when im done. another good example is the navigation add. its useful, but sometimes i don't need it. this would be a great feature, especially since the devs have been changing how the ui looks each update lately, this would make sense to be included in one of the updates!
--- Post updated --- And get the FPS in the Apps to be the same as your system. Instead of 30fps would be great. Maybe it's not 30 but it's a delay that you can feel if your used to quickly going through a lot of windows. Navigating the game menus is definitely off.
