Use case or problem
I usually have 2 instances of Obsidian open at the same time, editing 2 similarly-structured databases. It is hard to keep track of which one am I in at any given moment.
Proposed solution
Implement the conventional window-title-based document name/path indication like in other apps. I.e. show “MyObsidianDatabase - Obsidian” or “c:\Users\John Smith\Documents\Obsidian - Obsidian” instead of current “Obsidian 0.9.20” in the title bar.
