So I’m 100% with you that drag strength and the gumball don’t play nice together. Having to close the drag strength panel or slide it back to 100 to do a full strength drag, or do any up and down adjustment is tedious and has lots of clicking around. You also don’t know what percentage you need till you start dragging. Unfortunately, I don’t think adding additional handles to the gumball resolves this and would be a bit of a band aid at the cost of making the gumball very cluttered. One thing I’ve thought about, and maybe this is a crazy, is if we hook the drag strength up to the mouses horizontal wheel? So while you’re dragging you can dynamically adjust the strength?
I use a Logitech MX Master 3 and the horizontal scroll wheel is on the thumb. That way as you’re dragging you could adjust the strength using your thumb on that scroll wheel.
