i agree, love clip/manga studio’s drawing tools (though i still come back to harmony for still-work for the vector stroke quality/editability/color remapping features). the perspective ruler drawing assistants are also excellent, would like these in harmony (a note for a different feature request ).
i am particularly impressed with how smart clipstudio is at recognizing stroke-cadence grouping. if i am doing crosshatching, for example, and i want to undo some strokes, the software has a very good intuition about the “breaks” between my stroke patterns, and will clear a chunk of strokes that were made after the last break in my stroke cadence.
it’s not keeping track of the amount of strokes as much as the timing of my drawing patterns – if i make one stroke, stop, another stroke, stop, then undoing will just remove one at a time as usual. if i make one stroke, stop, then draw a bunch of strokes a bit faster, and stop, and do another stroke patch, and then undo, the last stroke patch is cleared first, another undo will clear the “middle” stroke patch, another undo will clear the first single stroke i made. it “just works”, and doesn’t get in the way.
nothing else i’ve used does this or gets it right – its either undo-per-stroke, or the timing pattern recognition is not in sync with me and removes way too much/too little of my drawing history. this sort of workflow feedback enhances the artist’s abilities and really boosts the value of digital drawing tools. it’s what elevates the tools beyond the physical limitations of ink on paper.
