Might want to check out Harpoon: https://github.com/ThePrimeagen/harpoon/tree/harpoon2

No comment on your one-file approach one way or the other, but like all of us, you will need to deal with tree-shaped projects, I've found Harpoon to be a good solution for this. Global marks can only get you so far.

Good luck with Audioscape btw.
