This is a must have extension for me!

I have a small problem though: if I remove the "session" checkbox and set an expiration date on a cookie, those settings get lost as soon as the cookie is set again by the server. In a case like that only the value should get updated. Or maybe provide a "lock" option to prevent a cookie from being changed at all by the server?

And a small useability enhancement: it would be nice if you could delete a cookie by hitting the del key instead of having to open the context menu. Also if the contents of cookie would be shown immediately when moving to it with the arrow keys, would IMHO be more intuitive than having to additionally press the enter key.
