I still think one of the neatest little concepts you've coded is your sticky button prototype. I've kept up with your work at least somewhat over the years, and there was a point at which you used these as the main navigation for mjau-mjau.com.
I think it would be wonderful if you gave us the option of letting our thumbnails function as sticky buttons. This would probably work best with (1) an "enable sticky" option, and (2) a numerical "stickiness amount" option.
Any thoughts?
