When I close the Miro window in the desktop app (Mac), it’s hard to whip it up again. I have to go all the way down to my Dock (sighh...) find the Miro icon, click on it, and go all the way up again (pheww...)
I know – life is hard, and I’m lazy… ;-)
Something like Cmd-N would be the obvious choice. (Cmd-1 is already taken.)
