Excellent :-)

I've been using Tasks in my sidebar for ages but this is a much more elegant solution, thank you very much indeed.

It's good too, to see you expanding your range of Panel extensions ... I was wondering, how possible it might be to do something similar with Drive?

I'm glad to tell you that I just release the GDrive Panel: https://addons.mozilla.org/es/firefox/addon/gdrive-panel/

Hope you enjoy it!
