Agreed.

As I mentionned when suggesting these keys, the use case for ShowIfRegistered 
is "Add To PlayList", e.g. you want RMB on a mp3 file to show "Add to Amarok 
playlist" if amarok is currently running, but not if it's not.

And you have a use case for ShowIfTrue in the spec already: "if .svn subdir 
exists".

IMHO the conditions are "AND"-ed. Any condition that doesn't pass disqualifies 
the action. That's how it's currently implemented, too ;)

Agreed.
