When you do cmd/ctrl+p and tyle “file exploerer” there’s the command “Show File Explorer”, it would be useful if that command actually hide file explorer when it’s already opened.
Proposed solution
Change “Show file explorer” command with something like “Toggle file explorer”.
What do you mean by “hide file explorer”? You know that you can show and hide the side pane (where the file explorer is located)? You can also define a hotkey for this toggle.
