Allowing removal of pinned queries via hover control.

First off, let me express my comprehensive love of Kibana 3.

With that out of the way, let me describe the use-case:  I wanted a general dashboard that showed multiple pinned queries (so they are nice and short with the alias), that could be used to get an at-a-glance view of things, while having the ability to drill down (or, in this case, filter out certain queries).  For example, a single system might have haproxy, python and cassandra log events, and I'd want the dashboard to show all three, with the ability to remove hproxy and cassandra queries to view only the python events.  Does this use-case make sense?

The CSS styling could be better, but I thought I'd get feedback before diving in further.

Thanks,
