XENDAI  Oh, one more thing. When you say that the "+" button doesn't work, are you possibly using an older version of Bellhop? I'm assuming you're talking about the button below the sidebar, right? That has changed since version 2.0 so that the plus button is now a full action menu with options to add services, collections, etc.  
(Version 2.0.1)

XENDAI  I believe you were seeing 2 problems: one was due to a change in Leopard and the other was a bug in Bellhop. I think both of those have been resolved in Version 2.0.1 and you should be able to drag service packs into your Bellhop collections and they should show up in the Services menu now. I apologize for the inconvenience.   
(Version 2.0)

XENDAI  Sorry about the problems. It seems as though I introduced some last minute bugs that slipped through. I will hopefully have those fixed and another build available tonight. Again, sorry for the inconvenience.  
(Version 2.0)

XENDAI  I just wanted to let folks know that the perl plugin is now complete (please note that the perl plugin should be considered beta, and any feedback would be greatly appreciated).

Starting with 1.0.3, all plugins are available for use free for 30 days (Ruby, AppleScript, Python, Perl and F-Script). After 30 days, only Ruby and AppleScript will continue to work without a license.  
(Version 1.0.3)
