I would get on my hands and knees to beg for this. I want to fully switch from clip studio SO badly, but this is the one thing that I constantly that is missing!
Right now theres shortcuts for sizing brushes up and down. I would love shortcuts for changing opacity to be higher or lower.
Clip studio does it in 10% intervals, and also has it for flow %. I think procreate has it too, but only for flow.
Really anything would work. Flow, or opacity, any intervals, I don't care. I have hand motor issues so using the slider on the screen to constantly adjust it can be painful after hours.
Id love it if you could consider it! Art studio has blown me away, this is just one minor QOL thing that I miss.
