Thanks.
I'm also evaluating using VSCode (it's perfect markdown preview) and this plugin for easy image pasting https://marketplace.visualstudio.com/items?itemName=mushan.v... .
And I was also looking into using mkdocs for serving a bunch of Markdown files in a directory to a structured webpage including search (which works great it seems).
But I'm not 100% happy... does not eliminate all of my bucket list but is a pretty independent flat file format.
