Since I’m not a developer, all code changes are easy! 
But I am curious: I know that the gents over at zettelkasten.de recommend linking only the unique ID part of the title [[yyyymmddhhmmss]] (yep, I add seconds to my unique ID) in The Archive. However, has anyone played with BBEdit? Search is insanely powerful!
I discovered how powerful at work, when I got access to our codebase to update or fix UI text. Using BBEdit’s multi-file search, I can input any text and find it across hundreds of thousands of files. And I can change it wherever it occurs in those files!
As you can see, I can even use grep and save searches:
/Users/sylvaticus/Dropbox/zettelkasten
Bonus: It’s incredibly fast!
I think this frees us to change tiles and not break links.
Just a thought. I love BBEdit, but it’s not a great MultiMarkdown editor (only works with Markdown, and not well). Since so many of us mix and match tools, perhaps you’ll find this useful.
