The OP and your comment just made me cancel my Milanote subscription, export all my notes to markdown and start using Obsidian (to later experiment with this Reor).
As a side-effect, I just noticed that I prefer a long markdown file with proper headings (and an outline on the side) than Milanote's board view, which initially felt like a more free form better suited for unorganized thoughts and ideas for writing that I had (I use it for my fiction writing).
I still can have documents as a list of loose thoughts, but once I am ready to organize my ideas, I just use well written and organized headers, edit the content and now I have a really useful view of my idea.
