I was able to find it just now by searching for "Enhanced Note Mode" on Google.http://www.keithmcmillen.com/projects/q ... note-mode/
Oh, I see what you mean, the index page for all the projects has gone missing, which is linked to there as "Categories: All Projects" and is supposed to be at http://www.keithmcmillen.com/projects/
So that's a web site bug.
Thanks for bringing this up, I didn't even know there was a projects page.
Looks like one can still use Next Project to cycle through all of them.
