Use case or problem
When focus is on the sidebar, and you hit Cmd/Ctrl-W, it closes the “outbound links” pane, or whatever is currently selected. The only way I find to get it back is “undo”, but it does not work if you do another action in a different area.
Proposed solution
Not have Cmd-W close the sidebar “tabs”.
Current workaround (optional)
None I know. Can’t reach my backlinks anymore
