I use AE every day for more than 15y and I realised there is one thing I really hate (ok, maybe one of two. second is endless window menu when you have lot of comps opened and need to run script at the end of the list. Even "better" when you have more than twenty scripts installed).
Everyday I literary cry and asking "why?!"
My workplace looks like the first image. And every time I onen new viewer or just drag any panel to make it bigger temporarilly and return it back (comp panel up to show more layer, or viewer to see more, etc) it totally mess up my arangement and I need to fix panel sizes over and over, hundred times every day..
I am used to use workplace presets, but it is not comfortable to wait until the whole panels setup load and draw.
There should be icon on every panel to prioritize maintain its size, or just size all panels relatively to the one you resize, or maybe anything else, but actual state is something made me mad.


Every time I change temporary my panels layout and returning it back I am ending with something like this (look at left side, the project panel, effect panel... stay stretched and need to be resize):


So, please. Make the panels layout more smart to avoid needs repeatedly correct their size. If they everytime you change layout will tends to restore their initial position instead of staying at last position, it will be GOLD!
