Joplin looks pretty damn good, my question is about the diagram function - basically, I take on more than I can manage, and have made my life a bit of a tangled hellscape. I’m looking to visually organise the physical projects I have started, and see which parts are holding up other projects. Essentially, columns of blocks for steps to complete one thing, each block being its own note, and visually showing if there are steps in other columns on which this block depends, or depends on this. Can it do that?

The way you describe these programs, and their websites suggest that they’re actually going to be way more useful than just my intended use case, I’ve never really considered replacing my basic notes with something like this. I used Evernote for a while, but they made more and more features paid, and it got much less useful in comparison to the iOS notes app, so I’ve just stuck with that for ages. What you say about a mature app with continued support really matters. Photobucket are working their absolute hardest to prove that point at the moment.
