Use case or problem
When you want one of your center panes to allow you to see through to an application/desktop behind Obsidian. For example you are working on a design in 3D or paint application, and want to layer Obsidian on top to take some notes.
Proposed solution
If there was a transparent pane mode, accessible via 3 dot menu or hotkey, being able to see through an Obsidian pane while keeping side panes would be possible. It would also allow you to hide side panes further revealing the desktop/application behind Obsidian.
Current workaround (optional)
Split applications and work side by side.
Thanks.
