At this moment in time personally I'm not so fussed about not having a Widescan ability.
But, map marking I do want! The maps for areas are huge and trying to remember where you have seen certain mobs, harvesting points etc is a pain without being able to put a little tag on the map. It would be nice to have a similar function in FFXIV to show map marks made by NPCs for guidance, and also personal map marks that you can name as you please.
