Cool extension. Was thinking about something similar, but laziness took the best of me.
As new user I have to report, that in latest Chrome release you cannot double-click on non-store-approved extension file any more and instead I had to:
- Open Tools -> Extensions page
- Drop .crx file from download bar onto Extension page
in order to install it. Small annoyance, hope it doesn't hinder adoption.
And last but not least, I took the liberty to add your site to Tagpad
