* DnD code doesn't currently support re-checking for only move or copy allowed - assumes both. Should be an easy fix.
* In cases of card->mailing list and read-only item-> anywhere, "copy" should be the default action. In other cases I think it should be move. I think this can be done within the limits of the existing code.
== Collected Address Book Removal? ==
CAB = Collected Address Book
PAB = Personal Address Book
Drivers:
* Thunderbird doesn't want to keep the CAB - the default is to collect to the PAB. (see [https://bugzilla.mozilla.org/show_bug.cgi?id=267877 [bug 267877]] )
* SeaMonkey also has the default to collect to the PAB.
* Keeping the CAB as it is means that users who don't use it are forced to have an extra address book [https://bugzilla.mozilla.org/show_bug.cgi?id=171125 [bug 171125]]
* Keeping the CAB as it is also gives us a little bit more bloat that we don't necessarily need/want.
There was some discussion quite a while ago about what was required and SeaMonkey was thinking of doing something slightly different which I haven't got logged. So the solution below is what is sensible, but SeaMonkey may want to add something to it.
==== Solution ====
Remove the CAB specific bits of code, so that:
* the CAB is no longer forced by default
* it can be deleted if required
* BUT existing CABs will still be loaded/useable etc (and of course deletable!)
