My love of outliners used to know no bounds but I have to admit my ardor has cooled somewhat as wikis have taken over the role outliners used to play in my software toolkit. Still, I can’t resist tinkering with ones new to me as I discover them. Today I found keynote, an outliner/notebook type app which is most easily compared to products like Circus Ponies’ notebook and aquaminds notetaker. Keynote is for windows only and is pretty featureful – a tabbed interface, the ability to nest notes inside each other, encryption, an API to build extensions and a developer community supporting their creation, drag and drop support, plus a ton more. I think it’s fair to say it doesn’t really come close to notetaker or notebook on a feature basis despite all the aforementioned, but free is free and plus it runs on windows. If you haven’t taken to wikis as a model for your personal data storage needs, or if you’re a fan of outliners, check out keynote.
