nvALT is good software. Its a simple note taking app, a fork of Notational Velocity. The key thing is it is very simple. You have a bunch of text notes in a bag. You edit one note at a time. Notes can be stored as text files in Dropbox. It autosaves as you type and has a simple navigation search UI. That’s about it.
I’ve tried a bunch of note taking solutions. Either they’re too simple and unstructured (like a simple text file) or they have too many features with a busy UI (like Evernote). nvALT is just about the right level of complexity. I use it mostly to track projects. One note per project, like “blog about nvALT”. Tagged with category (“blog”, “code”) and a numeric priority. I also have a top level Tasks that I prepend the day’s action items to.
nvALT includes a MultiMarkdown formatter with live preview that is useful enough to, say, write blog posts in. What I really wish it had was a simple WYSIWYG editor with HTML output. For some reason there still is no good simple visual editor in the world that spits out clean simple HTML.
