I have written a very simple plugin that provides a linked title tag on every page generated by GMail.

Example:
Home > Webmail > Addresses > Add Group
(appropriately linked, of course)

I have attached the plugin to the post. This is a first version of the plugin, and there are probably some bugs in it. Also, I might have forgotten a page or two (there are a lot of pages...)

Attached is the plugin, plus a screenschot. Feel free to use it on your site. If you find bugs, please tell me.
