This may already be possible. I’d love to be able to have only certain actions available in particular workspaces. For example, I have a writing workspace, which I use only for writing articles, letters, and other long form stuff. It would be great to see only markdown and editing-related actions in that workspace. No Twitter, List in Reminders, send to Fantastical, etc. I think a lot of users would find that helpful. Is this possible? If not, can we make it a feature request?
This is coming, through scripting in one of the next versions. You will be able to choose which workspace, set keyboard and set action group.
