The "export action" function is neither dangerous nor doing anything 
special at all - quitting Remote Buddy performs the exact same 
operations - just to a file in your preferences. I'm keeping hundreds 
of actions in the Behaviour Construction Kit without a problem. And 
the BCK has no real limits as to how many actions it can keep - it 
uses standard NSDictionary and NSArray objects to keep track of all 
actions and behaviours in it.

If you can give me more info on what problem you were experiencing, at 
which occasion and what actions on your part lead to them, I'm all for 
taking a look at the respective code.

Best regards,
