Let us compile a list of D3 annoyances.

Not having infinite range on inspect.

When I'm in a group and looking to see if I should vendor/melt something it'd be nice if I could just check my buddies gear to see if they could use it rather then linking/dropping it and asking them.

You know, that's something I could get behind. I know when playing with Quark or Tal, we usually have a constant back and forth over what items might be useful for the other character. This would certainly alleviate that.

If you're close enough to them, you can right-click on their character image (top-left of screen) and choose "inspect". That'll show you their gear.
