One of the best features about the EGP is that you can put controls at various levels of a nested composition. While designing, I might want something immediately accessible, but when I start to animate, I might need more controls and some of the same further up.
Users already have this functionality but unfortunately, its very laborious. A simple way to say "this control" should be "surfaced to the top" would mean I can always see that particular control no matter how many times I precompose something or move things around.
Its a small quality of life update but one that I would truly welcome. It shouldn't be a global on/off, but rather selective to the particular control in need.
