I consult for clients within their workspaces, I have three businesses myself, and I have personal to-dos that I'm managing. That makes for a lot of switching workspaces to keep everything up to date.
To some extent, that's inevitable, but once I've updated all my tasks and projects, I should be able to go to a single homepage and see all of my tasks and calendars for the day in one place.
PLEASE add this, though I know it's probably a big ask from a technical standpoint.
