i miss "show current tool presets"

yes i know it's still there, it's just i finally got what ive wanted forever, to better sort brushes/tools into folders. but i didnt realize how lazy i truly am. I wish with brushes, that it would either highlight, or only show the brushes of the current preset.

should i just go make a folder for erasers, SURE. but i am so lazy to look for them, i just make a layer mask and keep a brush in hand.

also i should just start a new thread, but does anyone have a favorite app for using ipad pro as tablet for imac and does the pressure sensitivity translate?
