Explain the problem as you see it
Sometimes I close the panel and would like to re-open it with a simple shortcut. However, this is not possible, as there's no command to re-open recently closed tab.
Why is this a problem for you?
I can't easily re-open a panel.
Suggest a solution
Have a command you can assign to a shortcut or provide a functionality of out of the box tied to a shortcut people have muscle memory for (CMD + SHIFT + T) to re-open previously closed panels in the same panel location they previously were. There should be a buffer so that more than one panel can be restored.
