Admin panel for Listings

Hello,

I find the information available in the admin panel for the listings to be too short.
I would enjoy more data for each listings.

Example :

* Real first posted date
* Last update date
* Listings lives until - date

Especially the posted date, it should never be changed.

Also one question,
In the Admin Panel, Configuration/Listings, there is this option: "Update posting date after plan upgrade"

What is the exact impact of Yes or No?

If it is on "No" and a user select to upgrade an existing listing, it means that the day counter until the listing is Inactive is NOT reset to 0?
So if someone buys a "upgrade plan" 1 day before the end of listing live, it will be featured only 1 day?
Am I right?

Thanks,

Any ideas?
