Unlike other similar software that I have used before, Krita is by far the most customizable. So I presume, everyone have different UI elements layout depends on their works and preference too. Though I stick to almost default looks closer to that of the older version with Color selector and overview at the top right and layer, brush, and tool option grouped together at the bottom right.
Animation assembly (ie: drawings with pen/tablet are finished, I’m processing everything that is easier/faster to do with keyboard/mouse on a large monitor and with high CPU/memory available)
Yes, it works ok. A few problems with the layout and menus, as well as with brush and bundle creation, but mostly, it works nicely for drawing and painting. The paintings in my portfolio here were created with Krita Mobile.
