It's hard to believe this isn't an option yet. If I don't add things in the right order it can be extremely cumbersome to create a whole new set of controls that you have to click 3 times to move one position up or down when you want to move it up or down 30 or so places. Apparently there used to be functionality where you could move them up or down using CTRL+Up/Down keys but it was removed.
@vwyankee thank you so much! This has saved me a lot of time ordering things in my application. It's incredibly difficult when you're building mock-modal windows and you have to change the order of things.
