Focus mode
Explain the problem as you see it
I often have two conflicting goals: First, I want to focus on just one page/node and close/minimize everything else. But second, I want to keep multiple other nodes closeby. Toggling between these two modes of difficult.
Why is this a problem for you?
It's a focus/time/effort issue.
Suggest a solution
I'd like a focus mode toggle for individual pages, where the focus mode on would use all screen space for that one doe, and focus mode off would return to the previous layout.
