Another side project I've been tinkering with involves creating something like http://www.gnome.org/projects/tomboy/
Basically, it's a notetaking application for Gnome which amazingly does not have a Windows port. Under the simulator, it works great... but I didn't want to have to open up Virtual Box to try this out. So, over the last couple of nights I used their basic interface to create my own take on it.

Basically, it is a plain text Wiki-style version of Tomboy. No spell check. If you create a link with MixedCaseLikeThis and click on it, you can jump to that link by clicking on it.
You can also search your notes as well...

And this has come in handy already. Finally, all this stuff is up for the taking in the icon part of the taskbar...

Anyhow, it uses SQLite as the database back end and VB.NET in the front. I tried this puppy out with plain vanilla Mono and it crashed without making a sound. I'll have to sneak a way to get it to work at some point.
In the meantime, if anyone wants this, let me know. It is very rudimentary and as in all developer tools and itches, it is pretty sparse in design and functionality because I can make it do what I want later. The Gnome usability, although limiting most of the time, is dead on with this application and I'm wondering how much of this I can use in new projects down the line.
