I just realize I could quickly see the integrity (via color square) and mass of items on the ground just from the scan window. This should put an end to accidentally equipping 2% legs after a fight or getting stuck staring at the integrity raw numbers because I don't see the percentage bar right next to them ... (which i've done too many times in the info window and I don't know why but anyway).
That's one of its purposes, yes :)
Would be quite annoying picking up after a battle without it--I'm surprised you've made it this far without having brought up this annoyance before!
(Side note: While in some regards it would be nice to have this information available direction on the map, that can greatly increase the amount of clutter and reduces overall readability, so it's better to show only names and ratings on the map, and color by general category, to allow quicker parsing of what items you may be interested in, then allow for confirmation of the details in the scan window as a secondary check.)
