I think this should be the main 2.8 topic, being more important than left right click select 
I wasn’t aware of this thread and I again reported the situation: Blender UI paper cuts - #1210 by RiccardoGagliarducci
We love Blender because the interface was:
- Non overlapping
- Non bloking
- Non modal
as commented in
Looking the proposal I’m really not happy about having something on top of my content (popup, popover, floating windows, …): I really think that NON overlapping is a very good idea worth keeping. I vote for solution A or C, really does not matter if configuration is on top, right, left or bottom…
We have many examples of big software (ex. Autocad - overlapping/blocking, Photoshop - overlapping ) that moved from an overlapping situation to a better one, where the top bar is really the reference of the current status ( event if they do NON have multiple windows/areas for the same file!).
In the open source world The Gimp made a similar path, allowing single-window mode.
Freecad, like many industrial cad, does not allow multiple works at the same time (like or you model or you do uv, no way having both on the screen).
We have also interesting examples in open source world where Krita Pop-up Palette makes the tools configuration right under the mouse (like Z-Brush or like our pie menu…).
So let’s keep the good (non overlap) and skip the not applicable (unique topbar)!

But, in the meantime that a better solution is found, is there a bare minumum solution that makes every one less sad?
I do think that the top panel has some main issue but, as first step and getting heard, what do you think about starting to agree to have, at least, the top toolbar updated when the mouse changes window, to have - at least - a coherent state (as it is the bottom bar that suggest mouse commands)?
Thank you,
