[Plugin: Taxonomy Drill-Down] Tags drill-down works only for two terms!

Hi, this is really great plugin, thanx Scribu.

I noticed that categories list drill-down works ok, however if you try the same thing with tags, you can choose only two, and on third click you get posts listed under third tag only.

Second question relates to this solution applied to older version of this plugin, when you dont want to turn off other terms, is it possible to do so in this version?

Also is it possible to sort other posts with closest match to chosen query, for example posts matching two of three terms?

Thanks again!
