In Trello I was able to hover over the task and then hit "d" on my keyboard, and it would bring up the date selector. I got very used to this . . . and it's killing me that I can't quickly get to the date anymore. Since Clickup has Hotkeys, please assign a hotkey for date selection.
p.s. I realize that "d" is already in use for Dashboard. My suggestion is to use something like "h" (home?) or "alt" for the dashboard, and reassign "d" for date. Even cooler would be to let us assign our own hotkeys :)
