Driver property in panel on right

Yeah... Blenders UI is a mess - it seems there isn't a proper design how things are handled and how certain things are presented. Showing a bunch of transient data related to some things seems to be an issue. Basically Properties window ofter does that, but mostly for objects. I doubt they would implement your suggestion, as there already is a drivers window. So what would this be? It ain't quite tool settings, like what you get after doing bevel or something. And the whole N-panel feels still like a mess - basic transform stuff in one tab, then some add-on UIs and whatever else like tool settings. And these windows like Driver Properties are annoyingly transient, why couldn't they add a header bar with a 'x' to close it, like pretty much every other windowing system has, now it simply vanishes if you accidentally move your cursor outside of it.
