It would be nice if I could connect my Apple-calendar with it as that's what I'm using personally.
Ctrl+space short key is nice but canceling it with esc doesn't work for me at least but I have to open the app to get it closed.
Also - I'd use it so much rather if it would be more independent from google. I switched off from Gmail this year so commiting to Google ecosystem this way isn't so nice.
Anyways, all the best for you. Let's see if this will be actually useful for me.
