Here's another thing about tree style note taking and the structure of knowledge that maybe bugs me a bit more than it maybe should: Yes, for about 95% or (much) more of nodes the structure is hierarchical, but there's still a somewhat significant amount of nodes for which the conceptual structure would actually be a directed graph (here's an extreme but common example: You want to make a list of cars. Do you group them by manufacturer, type, price ...? Not at all? That'd be extremely hard to navigate. You'd also want to be able to easily change it, right? Another example would be general cross-linking). Have you thought about this before? Would it be feasible to implement something like this in your app? Does anyone else know whether there are tools out there for this already? I wouldn't be mad about a mind map view (that is not absolute garbage because it's a swing app that's ugly and only available on desktop linux or offers per node styling options [I see how it's good for presentation, but it's just terrible for pure structure keeping] ...), but I'd prefer the main view to be tree-based as it's by far the best representation (I have found so far) for the by far most cases.
