I think this is a tricky one. Obviously there's significant potential for data loss (and confusion) if you allow a multi- custom group to go to single record. Very early on in an installation, before the data is populated, I understand wanting to shift from multi- to single- (I've had clients need me to do this). But once you have data in there, it's pretty difficult to migrate to single without risk. Especially since the average user may not have thought through the implications fully.

So that's just to say, I don't really think you should be able change that setting through the interface.

I do agree, though, that you should be able to delete a custom group without first deleting each field. Obviously there should be appropriate warnings and all. But it's pretty tedious to have to go through and delete each field.

On a side note, eventually it would be nice to have the ability to handle actions on multiple records simultaneously. For example, to select six fields in a group and then disable them, or delete them. Moving fields from one group to another would also be a nice feature (with all the corresponding data).
