@firefly-factory krita mutual!!! i use 2 customized workspaces like this, top is for the gesture sessions and the bottom is for colored drawing stuff 🤩 (sorry sorry i know you didn't ask but i just wanted to share 😅)
I use it mainly on an android tablet now (propped vertically on top of the desk like a desk calendar!) and i put most of the buttons on the bottom left for quick access with my thumb!
I also add or move around button layouts on the toolbar every once in a while to experiment if i could improve on the workflow more 🤔 absolutely looove that krita lets you do (mostly) whatever the fu you want with arranging the workspace 😌
i wish the brush size and opacity controlling rectangles could be made a bit longer though 🫠
love the undo -> two-finger tap and redo -> three-finger tap functionality. Only downside is that my hands instinctively double tap on other note apps to undo as well 😂
