I'd simply like the swipe up to open app drawer gesture, just like the pixel launcher or every other recent launcher. the app drawer button is old and not comfortable. the swipe up on the dock can live together with this gesture!

Great that this feature is planned. Do you have in mind to let the user use the spare icon in the lower screen free for use to an additional app icon as it's not needed when opening the app drawer with vertical swipe?
open box of apps like a Pixel launcher
