It's always bugged me that when I'm on the fly using ClickUp on mobile, the one holdup is that the planner just shows your events, nothing else. You can 'open' them with the view drawer, but they don't show the video call links, you can't view or open the tasks in them, and you also can't create the tasks and time blocks and events from mobile, either.

Those abilities would allow you to do task execution on the fly inside the planner, which especially for my use case in outside sales, would be game changing!
