Keyboard shortcut for Stoke Width is missing.

I use a tablet with a Mac (not iPad) for my design work. Usually, I can change the brush size by pressing a keyboard shortcut while dragging the brush in many illustration apps. I think this feature is missing in Vectornator 4.7. There is no such keyboard shortcut.

Even worst, the Stork Width slider is missing too. Now I need to tab the tiny up/down arrows to change the brush size. It is just too slow.

I hope the Vectornator team could introduce this feature soon. Thank you for your great works always!
