Currently through the 7.94 update both "Primary" and "Inactive" boxes can be checked in the same time, which is counter-intuitive. I would like to purpose that when a "Primary" phone/email/etc. is marked as "Inactive" the Primary listing will be automatically removed. That the code is changed to reflect that these two categories cannot be selected at the same time.
We should also add to this that, when adding a new phone/email/etc to an empty tab, that entry should automatically be marked as "Primary".
This is a no-brainer! In fact, you could almost consider this a bug..
