Are there any plans for a Prince GUI for OSX? For my non-technical colleagues it would make learning to use Prince far less intimidating.

Not at the moment, sorry. There is just too much to do!

In other contexts, we've had pretty good luck just making some little Applescript droplets that you can drag files onto.

Thanks! I was just checking before we make another plan. It's certainly not critical. The Applescript droplets are a great idea.
