This is a widget for all NaNoWriMoers out there. It shows the countdown to the end of November and a nice bar with your progress.
You can update the progress by either entering the count manually, dragging a pure text file onto the widget or by dragging the text itself onto it. Dropping text adds to the count rather than recreating it so you just have to drag and drop the latest writing.

You need superkaramba 0.37 or higher for this to work.
