It's possible that Bez is one of the problem cases. There was change between Bibble 5 and ASP as to where the selective copy got it the plugin name from. B5 used plugin name and ASP uses plugin group. Some smart people used the same name for both, but I was not one of those smart people. In fact the old B5 plugin tutorial encouraged you to have different names.
So I had a choice when I migrated Bez to ASP: whether to do what you want, and which would have meant that we couldn't import B5 settings, or to leave it as it is, which meant that the selective copy dialog said "ferd" rather than "bez".
I have had a discussion with Dave from Corel Labs about this, but nothing was resolved. He said that it's possible to argue that this change is in fact a bug in ASP, but it's also possible to argue that ASP fixes a bug in B5. I was advised to contact Jeff to ask for a change back to B5 behaviour, but I've heard nothing in response.
If I was to change now I would break the entire B5 import capability and invalidate existing ASP saved settings. I guess I could create a version of Bez with this stripped out, but would only do so if there is overwhelming demand.
Such a small thing with such large implications.
