We added a new UI system this week. You'll now get a tooltip when you look at stuff you can use. There's 3 main tooltips right now.
This one shows when there's only one action. Pressing use now does that action straight away instead of popping up a menu.

Secondly, this one shows when there's an item you can pick up. Seeing what the item is before you pick it up is pretty useful :)

Thirdly, this one shows when you're looking at an item that has multiple options, which will open a menu when you use it.

This makes doing things in the game feel a lot more polished. Also, don't worry.. this whole design is kind of placeholder right now - we'll hopefully be updating that in the near future.
