Hi,
I started with version 3.0.1.1. and am now on 3.1.2. and am generally in love with Krita.
BUT, I find it a strange animal because in watching a tutorial using an older version (2.9?) there seems to have been a certain useful feature that was REMOVED and I can't understand why..

In the tut he could float the "brush settings" window making it easier to get a different colour from the palette to use on the scratch pad.
You can't float this window anymore. At least I see no way of doing it. This is bothersome.

In the tut he was able to grab the "overview docker" and move it to the left side. I can do this but the size is not constrained. The docker takes up the entire space, overlaying the Toolbox. His stayed the same size leaving room between it and the Toolbox. Is there a configuration setting for this?

Yeah... I had to remove that functionality because the popup menu on the popup brush editor no longer registered clicks after the port to the new version of Qt, our development toolkit. I never managed to make a small enough sample that showed the bug to report the bug to the Qt developers, so I couldn't do that.
