In the game it would be very useful if the blue highlights showing selectable things were also used to highlight the current selectable thing when more than one can be selected. For example, if I am standing in front of two pigs (1 and 2), when I press "enter" I envision the following:
1. The existing "Choose the the thing you want to interact with." dialog would appear.
2. Instead of the blue highlights disappearing from the actual things, the matching thing would remain highlighted. For example, Pig (1) would be highlighted in blue.
3. When the selection in the dialog is changed using the keyboard/mouse the highlight would change accordingly. For example, when Pig (2) is highlighted in the dialog, the blue highlight would switch to the other pig.
This would make selecting the right thing much easier when multiple things can be selected.
