I agree that Texnotes is a little too cutesy. It's not just the bear,
it's the liberal use of pastel colors.
After finding that OneNote didn't quite meet my needs for organizing my
dissertation, I made a pretty exhaustive search of hierarchical
information managers. I finally settled on CrystalOffice's Maple, which
is far from perfect, but meets my needs. It has a number of drawbacks
and a few bugs, but I chose it over Hyperclip because the interface is
less cluttered, it seems more responsive (snappier when changing notes)
and it has a few features I prefer (though Hyperclip has some that Maple
doesn't -- they're both worth trying out). Both are missing some
features I desperately want:
1. the ability to define styles, ala Word, and have the style
definitions remain stored with the document. Changing a style updates
all its occurrences within the tree.
2. nested lists within a document.This is especially annoying because it
should be trivial. Any RTF document editor should support this.
3. custom node templates, such as for 'todo lists' with check boxes and
contact lists where each contact is a sub-node and information is filled
in as forms which can be customized or defined from scratch
4. a built-in web browser (acting as an IE wrapper) such that nodes can
be hyperlinks to web pages, thus remote, dynamically changing content
can be accessed from within the software. Essentially, this would make a
node simply an http bookmark, but I'd find this incredibly useful.
I list these so you know what you're getting into. Many people will find
OneNote a better solution (though it doesn't do some of these, either)
