That's completely do-able without me changing a thing. That's what CSS is for ;) I specifically didn't include any styling as I think that makes it much more flexible. I've included hooks in the code so you can pretty much style it however you want. I'm not enforcing the layout it has on the demo pages, It's pretty much just default blueprint style. Though perhaps it would make sense to post up a side by side version. > Also its better to physically remove options from selector "From", > instead of greying them, once they are "moved" to selector "To". Not in all cases, though I'll admit it would be good to add this as an option (disable or remove). I'll see what I can do. Thanks for the comments
