For the highlight interactable key (tab), I suggest the "compromise" that it be items within about 10 feet (unless hidden of course), but yes it is an issue.
Near the Sussur tree in the Underdark, I past around it about 4 times. Every time, I found new loot containers that I just could not spot visually. In fact, I had to read a tip on the Internet to go back a fourth time and finally mouse-over the Sussur bark (a specific area on the entire huge tree).
It makes my completionist playthrough much longer than it already is :P
