Thanks for mentioning Joplin! Personally I don't use it as a Zettelkasten tool, but I tend to use it to throw ideas in lots of checkbox lists and sub-checkbox lists, which I guess is a similar concept.
Instead of linked notes, you end up with a hierarchy of checklists, and when you go back to it you can easily check what wouldn't work (which grays out the sub-tree), or what's been done, or move around the lists. It works well for me as it means it's all in one note so you get a quick overview of the whole thing.
