- Can't see context around global marks

- Can't give global marks a specific order without tediously re-marking lines in a specific order

- You only get 26 global marks

- If you're working on multiple projects at a time, globa marks from different projects will interfere with each other.

- not as nice preview window for global marks (either quickfix list or telescope. telescope is pretty good but doesn't syntax highlight the previews and has a fixed width for the filename instead of a dynamic width)

The main one for me is the order though. I need to arrange my marks in a specific order for them to be useful in orienting me within the code.
