WebUI Advanced Filter // mod: collapse filter section

So, this is something that should be an easy fix. When using the Web UI you can create a fairly complex advanced filter

However has you start adding rules, the visible area below the filters gets smaller and smaller. Since this area is a fixed width and size it can easily reduce the visible area by 1/3.

Having the ability to collapse the filter rules down to a small area at the top to view the list would make the UI accessibility much easier.
