Would it be possible to have a link on the notification emails that goes directly to the plugin upgrades page? Ie. http://yourwordpressblog.com/wp-admin/plugins.php?plugin_status=upgrade
Right now there are links to the the public facing blog and a link to download the zip files from the Plugin Repository, but no link to anywhere in the backend.
PS- I tried editing this into the plugin, which I did successfully, but it created some bug where I got several emails a day.
