I’m also curious how color management will influence color picking, mixing, modifying, etc? Is it similar to what is described in these krita docs? Gamma et linéaire — Documentation Krita Manual 5.2.0
I also revisited my early flat-brush problem and came up with a hacky way to get it working (somewhat). The new brush locks rotation (direction filter) after a very short distance (stroke input) to avoid buckets mixing up on rotation. During that distance the smudge length is set to 0, which - as I read it from the C code - already resets a single bucket. The short moving distance is also needed for the user to get the rotation right easily after pressing down the stylus

In the end it’s very hacky and I dont like it very much 
but I’m using it in a current painting. I guess some input for drawing-angle change might be useful / needed for this to work without having to lock the rotation. But I imagine that to be quite bit messy too since it basically needs to remember the drawing angle for many dabs to be able to look back based on some X distance or something.
Do you have any thoughts on this / a different suggestion? I never got any round brush with manual dab placement to draw very smooth/clean strokes like this simple, flat one. Might be usefull for your brushes as well, as they seem to have the same issue…
edit: brush is quite sensitive, you might have to press very lightly
