Thanks for the feedback! I guess this plugin is a bit specific to how I use Obsidian [1], as I don't rename my notes quite as often as others do.
As I mentioned in the post, my main use case is being able to quickly reference notes in my hand-written journal. I've also used it a few times in some personal shell scripts.
Probably not a very useful plugin if you already live entirely in your Obsidian vault, though - in there good old [[wiki links]] are much more useful.
I've left a few comments so far on the rename problem, but yeah, it's a hard one to solve. I'll try to think of ways to improve it.
