There's no reason for every single property tab to be expanded by default. There is a ton of information in them, especially with private variable inheritance, numerous behaviors and effect stacks, etc.
Also, managing anything in the properties bar is extremely laggy when there's a lot in there.
It would be great if we can simply right click > collapse all to get our properties bar nice and neat, and only access the information we need. Even better if we can make them collapsed by default.
