I like to keep notes simple. I have a ton of .txt files littering my desktop. I'd love to find an app like http://getxpad.com/ (Mac Only) for the PC. Evernote/OneNote are overkill.
Ideally I'd love to find an powerful notepad app where I can keep the notes in a sidebar and have the main window for the note content.
Does such a beast exist?
I can't think of anything that matches all your requirements off the top of my head. Have you checked out http://www.osalt.com/onenote ?
One tactic I've adopted is to use a Google Doc for all my "scraps" that I would normally litter about my desk on Post-Its. :)
I suggest "Notecase", which exists for Windows, Linux and OS-X. Data is fully interchangeable. The tree on the left (titles) is hierarchical. Too many levels complicate things.
