Suggestion: Duplicate field group OR change title/ID on import/export

Related to the issue I just posted...

I wanted to duplicate an existing Field Group (because it had a field I cannot add to a new Field Group).

I think this feature doesn't exist, but there is an Import/Export field group.

I did not want to import a field group with the same name/ID (what would happen?), so I went to edit the .dat file.

Of course when I open it, it's encrypted or otherwise not editable by me.

To be safe here's what I did:

• temporarily changed the existing group's Title & Slug
• exported .dat file
• revert the existing group's original Title/Slug
• imported .dat file, which has the "temporary" title/slug

This worked, and I just edited the fields in that group. BTW, the custom taxonomy field works in this "cloned" field group.

SUGGESTION:

To avoid this extra work I did, maybe

• Provide instructions how to edit the .dat file
• A "Duplicate field group" link would be most convenient
• Otherwise allow Title/Slug to be changed before import
