I'm filing this as "Quality" because it's a Quality of User Experience issue. For those of us with aging or deteriorating eyesight, or for those of us using screens that are modern-size (my Apple Studio Display is 5120x2880), the current tools appear far too small. A usability design goal should probably be to make the tool space and icons scalable so that they occupy approxiately the same amount of horizontal area, no matter the screen width. Similar to modern, scalable web design, it does little good to cram all the necessary tools into a smaller region of the screen and to keep the tool name text tiny and tooltips tiny. Please update so that I don't have to switch to a non-optimal, pixel-doubling clunky screen mode just to use this one piece of software. Other companies have figured it out and I know the brilliant minds behind Painter can as well.
