Hi,
When developing UI in create you need to repeatedly click both left and right side of the screen a lot.
It would be more efficient if you could navigate the UI “tree” of components with some hotkeys.
For example W and S for up and down on the same level.
A and D for parent or first child select.
Would save some mouse hand strain 
Edit: and hold shift + hotkey to move selected component
