Created a video on how to modify Krita interface for tablets (especially for Samsung tablets as that is what i use) for the maximization of real estate and distraction free painting.
This is all achieved in the current version of krita (5.1.x or 5.2) and should be valid until an interface for Tablet / Mobile is created.
Video is created a tad bit in a hurry so if anything is not clear, may ask.
Edit: Second part utilising upcoming krita version is uploaded
