I rarely use the preview pane. So it’s closed most of the time.
But every time Obsidian starts up, the preview pane starts open.
I expect it to remember that it was closed on shutdown, so that I don’t have to close it again on every startup.
That’s strange. My panes reopen as they were on quit. Do you get that behaviour if, say, you quit with 3-4 edit panes open?
I also have the same issue on macOS 10.14.6.
Answer my question above?
Also, folks, please use the bug report template. Those questions help us narrow down your scenario so that we can fix things!
Update: the preview pane stays closed now. Not sure what changed.
So for me the problem is solved.
