Ah, sorry. I focused too much on the "seriously considering moving back to Markdown-folder backed by Dropbox". Joplin does support note linking (https://joplinapp.org/markdown/#links-to-other-notes), but it is quite clunky, to be honest. However, it does look like it's being addressed soon (https://discourse.joplinapp.org/t/syntax-to-link-notes/5264/...).
