I have really just started playing around with Multi Commander but I like it so far. I like having a toolbar of custom commands so I have beem messing with the quick launch bar. I created some user defined commands and put them on the ql bar... they work as expected. But it seems that multi tags cannot be used as parameters for programs that are dragged to the quick launch bar. This is with 2.5.1 (Build 1114) and 2.6 (build 1142).
