Campaign list filter request

[mototom]

This is a minor thing, but can we please filter (or at least add a toggle to filter) the campaigns in Campaign Theater to only display campaigns for the system we're currently using?

It's nice that a campaign in the list can jump to whatever rule system it uses. But that's not how I'm typically working. One is almost always logged into and working with a specific ruleset, since the first thing you see logging into HLO is a set of giant buttons to select the system you're using. So far, I've never used the workflow where I go to campaigns to change my system and campaign. So the additional campaigns just become clutter.
