If Final Fantasy XIlI gets a remaster, what is the biggest thing it needs?

Me personally, I would say it absolutely needs Final Fantasy XVI's Active Time Lore. FFXIII has a very complicated lore, that requires a lot of reading to understand. And rather than scrolling through all the datalog to find the entries I need. I rather have ATL give me the most relevant entries upfront, at the moments I need them. The other two games in the trilogy could also benefit from an ATL, assuming Square Enix wants to remaster those too. Which I am certain they will.

Of course there are other things the remaster needs, like a Hard Mode, Chapter Selection and the ability to switch characters.

What about you all? Thoughts?
