A new build of programmers notepad is available - PN2 version 0.5.5 (herbie). Looks quite good and can only get better. Quite a few changes and bug fixes since 0.5 (the last development release) - including 'magic folders' within a project (a magic folder lists the files/folders contained within a directory on your computer). Read the release notes, or download from SourceForge.
I'm sure PN2 will be very good when the stable build is released.
