Like the title describes, I would like a extra column to be added to the codelist overview page so that, when applicable, you can easily view which codes are soon to be unavailable.
Reason for this is my last experience, where I couldn't figure out why my used codelist said 0 out of 400 codes when only 25 peoples had entered my campaign.
After contacting support the they said that the codelist had reached its max-publish date thus showing 0. I had forget that I entered a max date that's my mistake. However, it would've saved a couple hours of debugging and contacting if a max-publish date was shown.
This may not get a lot of traction to be added as a feature because it is a pretty niche problem, but people can dream right :).

Thanks in advance, and I wish everyone reading this a pleasant day!
