I really appreciate the new way PowerApps displays the list of screens but here are some of my suggestions on how it can improved.
Condense all items on start-up. To be honest, it gets very annoying to have to condense all items every time I open PowerApps, especially since I have so many items in each screen.
Drag and Drop Feature I know screen order doesn't really matter but it would really great if I was able to easily reorder screens for organization purposes rather having to open the menu and click "Move Up/Down" several times. (Ctrl + Y doesn't seem to have an effect) This could also be useful for objects for adjusting order on the z-axis.
