edit: They are case-insensitive. Ignore what I wrote below. I was wrong.
Why is this in “feature archive”?
My proposed solution is custom link like [[Something|something]] should be auto-applied. Basically when I type [[something]] (all small case letters), Obsidian should auto detect if there is already a document with the same name but different capitalization, for example “Something”. If there is one, [[Something|something]] should be automatically applied.
We are not computer code, case sensitivity should not matter when referencing other documents.
