I created a free "Daily Record of Events" (DROE) Tool to help with note taking in OneNote 2007. I also just updated it to add some shortcuts for fast Outlook (2003) task and message creation, as well as easy creation of "PigPog" tasks. You can find more information and download the tool here.
I'd be interested in hearing some feedback on the tool, as well as other features people would find useful. Some possibilities include support for EverNote (instead of OneNote), as well as an ASCII text-based DROE that wouldn't require any special applications. Thoughts?
