I've added it to the feature db but it won't be in 1.1, whose code is frozen. 1.1 was supposed to be released today but there were some last minute glitches with the reseller so I'm in a bit of a holding pattern.
So, 1.1 should be out very soon and I'll look into adding the ability to pause/stop Hazel in a maintenance release after that.
For now, I'd use the new feature in 1.1b4 where you can command-click the checkboxes to activate/deactivate all rules at once. You have to do this for each folder but it's better than one-by-one for now.
Hope this helps.
