Tension Software today released NoteList 2.3, the latest version of its note taking software. NoteList is a Cocoa-based application to manage various types of information in one place — it allows you to store searchable notes in a free format using full formatted RTF text and images. It is based on a list of notes on the left and the content of the selected note on the right. Notes can be categorized and filtered, as well as be searched  by category and keyword. NoteList is priced from US$20 and requires Mac OS X 10.4 or later.
