When renewing or upgrading a listing plan the start date stays the same and as such when people repay to renew their plan it is not raised to the top again as it does not read the date of last update of the plan.

This should when somebody renews a plan place it at the top of the featured ( or non featured listings ) this does happen and would get me mad if i was paying good dollars to renew a featured plan and the update was left buried in the depths of the deep ?

Is this how it is supposed to be / or how do I set things to be listed in date of added / last updated / renewed ?
