I like how when I hover my mouse over a tree or animal it will show an icon above them with either a broken heart, water drop, milk bottle, or meat letting me know what interactions I can perform with that object. I also just recently found out that you can click those icons and perform the requested action instantly (even from across the street in the case of animal actions).
But I find this hard to use on my 20 pigs in my pig pen, other pigs are always walking in front of the one I am trying to hover over and it becomes very frustrating. So I stand in the middle of all my pigs and press enter, which brings up a very handy menu that allows me to select objects that are behind other objects, this is great. However I can not tell which pigs I have already pet or nibbled, and so I choose one and press enter, already pet and nibbled darn, try again, already pet and nibbled too darn, rinse repeat. I am sure that I never actually nibble all 20 pigs twice because it is too frustrating trying to figure out which ones I have and have not already interacted with. Short of making a daily spreadsheet with all of their names and check boxes I don't know what to do.
So I would like it if those helpful icons that appear during mouse over would also appear on the selection menu while using the enter key to interact with objects.
