Thanks very much for doing this plugin!
I must say, I really like the fact that I can select from my export presets. This is going to be a veeeery useful plugin!
I'm curious if it's gaining in popularity - can you say how many downloads you've had?
In any case, I tried it for the first time tonight, and saw two anomalies that I figured you would want to know about. First, after I logged into pBase with the plugin, I couldn't see my list of galleries. When I clicked the popup, nothing happened. No gallery was displayed on the button.
Second, as soon as I pressed "Export", Aperture crashed. I sent the report to Apple, for what it's worth.
Oh,, I'm running version .13 with Aperture 1.5.2.
