This is absolutely the most useful extension for Thunderbird. The extension itself is really quite simple. It's one of those features that in hindsight seems so obvious to have in an e-mail client.

The only downside is it doesn't work 100% as intended on OSX. On OSX the XNote window opens up behind the Thunderbird window when you click on an e-mail with an XNote attached. So you have to get that each time. Also, the OSX window controls (Close, Minimize) are shown in addition to the XNote close buttons. So it doesn't seem quite as seamless. These are fairly minor problems, but they are the only things that cause me to give XNote a 9/10 instead of 10/10.

Hopefully those OSX issues can be resolved. In any event, keep up the great work!
