If I close a pinned pane and then reopen it with the new Undo close pane command, it’s opened unpinned, which means that if I then open another file, it will be opened in the latest pane, which I thought was supposed to be pinned.
When closing a pane, memorize the pin status, and when undoing a close action, make the pane pinned if it was pinned before closing.
Current workaround (optional)
Undo closing, then click the three dots icon on the restored pane and select Pin.
Which brings to my mind (again not so much related to the topic): If I quit Obsidian while having this kind of No file is open panes visible, next time I open Obsidian, those panes will not be opened at all, so I have less panes visible than what I used to have.
For some time now, whenever I open a note on Obsidian, two more empty panes are automatically opened (https://bit.ly/3f1K653 : “no file is opened / create a new one / go to a file / see recent files, etc”.
Each time, I need to close them. When I quit Obsidian with only one pane opened, the one I was working on, and then restart, those two empty panes are still there. Would you have a clue on how to fix that?
I think it’s a different problem. But a general thing you can try is to disable all community plugings you might have installed. If that doesn’t help, try to disable all core plugins one by one to see if one of them is causing the problem.
