Committed, thanks. I'll wait with adding a button to launch appfinder 
until it fully supports the other fields of te .desktop file as well.

There is a problem here that the dialog window is not available to the 
function; we should try and find a way to fix that, then we can use the 
entire window as drag destination, which would be nice IMO.
