Using Obsidian on 2 computers in a Onedrive folder, I noticed that when the same note had taken different paths on the 2 devices, a new note was created on one of them appending the other device’s name to the note name.
In case of heavy editing or a computer being offline for a long period of time, it might be useful to be able to automatically highlight the 2 notes’ differences before merging the edits.
