Faster editing in long files
This is an "under the hood " feature. I have this 52kb text file—and it just keeps getting longer. I've noticed that Noteplan has gotten sluggish when editing it.
I'm probably just going to split the file into smaller ones for now, but you might want to look into why Noteplan is sluggish in editing long files like that.

I don’t know what you’re already using for markdown rendering and it might be way too hard to try this but here’s an idea: https://github.com/johnxnguyen/Down This Swift library uses cmark for rendering markdown which is incredibly fast. I’ve used it in my app and I can say it is also very easy to render and use CSS with it.
