How can we improve WHMCS?

Please allow for the sale of TLDs that require renewal earlier than their expiry date and for WHMCS to ensure that all other features of WHMCS - such as invoice generation and Email reminders work with it.

To give others an idea of how widespread the problem is - the following is a list (I might have missed a few) that, to date, cannot be handled by WHMCS properly because WHMCS cannot accommodate the requirement for them to be renewed x number of days earlier than the TLD expiry date:
