How can we improve WHMCS?

More and more registries are moving from an auto-expire to an auto-extend model. This means that domain names are auto-extended by the registry by default - resulting in the domain staying "Active" indefinitely. Domains that have extended past their original expiry date without a paid renewal invoice should be flagged so they can be expired as part of a daily process, this probably requires two expiry fields, a targetExpiry and currentExpiry, when getting a status update from the registry:

Possible approach:
Prior to targetExpiry being exceeded, targetExpiry and currentExpiry is set equal to the current registry expiry date
After the targetExpiry date, only currentExpiry is set tp the current registry date if no renewal has been paid for
