Not sure if I understood it properly.
If you're saying that the quick menu is activated by a 4-Finger tap, I think that's not the optimal way to go.
If you're saying 4 finger tap is for costumizing then just ignore this post.
In my honest opinion, I hate the 4 finger tap on the iPad. You have to hold the pen awkwardly and spin it around to tap and sometimes it doesn't recognize it properly.
I think the way to go is a quick swipe with 1 finger. So ít will feel more naturally and you can just swipe intuitively in the direction of the function. If you use it often you will just know in which direction the desired function is.
Would make more sense since it is the 'quick' menu.
Or at least add an option to costumize the way how to access this feature with gestures.
Also with the quick swipe gesture for the quick menu:
- would be awesome if you can also place favourite brushes on the quick menu instead of just functions.
-> quick swipe to get to your main brushes
That would improve (at least my) workflow a lot.
Anyway, thank you for your work!
