I've been trying Obsidian, Foam, Dendron, etc., and most of these Zettelkasten-like editing environments have issues with relative links (i.e., they don't let you specify a base folder) and/or completely ignore front matter, which makes them hard to use when you've got 8000-odd posts across a big directory tree.

I've been resisting hacking my own, but I suspect I will eventually have to :)
Have you used LogSeq? Its "thing" is that it doesn't have folders, period. Your workspace is just a graph of files that reference each other. In the event that a page's name has slashes in it, the components will be treated as hierarchical pages, but that's more of an emergent folders thing than real folders (as changing the name of a page changes its own hierarchy without renaming any of its parents in the hierarchy, leaving the existing hierarchy intact)
True, Logseq is mainly an outliner. But you can enable free-form text temporarily by pressing t+d (toggle document mode). Alternatively, you can press ctrl+shift+p to open the command palette and type 'document mode'.
Since I rarely use it, I don't know. But ask on Discord. The community is very friendly and helpful there. You'll find the link to it on their website under Community.
Not the original poster, but my main problem install Dendron as a vacode plugin was sometimes my Dendron directory wasn't "Dendron", and sometimed Dendron seemed to load and do things when in directoris of unrelated markdown.
I never did figure out what was going wrong, but I moved to Obsidian mainly so I had a clear separate note keeping app.
if you have a public repo or an example note, happy to take a look at it. we've done lots of work on our markdown import and it should address a lot more cases now
