Notable is a great free markdown editor on GitHub. You can import regular markdown or Evernote files. All the files are stored in one directory and are grouped by tags. The tags can be hierarchical if you’re looking for that. Most of the time though the regular file search does great.

I find myself making so many small notes of how I did things at work or with AWS, zsh etc.

It’s a really powerful system while simple at the same time.
