I have noticed that (for example) when I hit enter with both a tree and a butterfly behind me and glowing, the tree comes up as the default selection on the list of objects to interact with. I think it would be much better if the default object was always the most mobile/smallest object (best sequence is probably butterflies > chickens > pigs > other players > all stationary objects starting with trees or whatever else is most likely to be desired for interaction).
My reasoning: if I am trying to interact with things quickly, I can usually just jump when I am near a tree and aim for the side furthest from butterflies/chickens to get the tree as the only valid interaction target and save me a keypress. However, it is really hard to isolate butterflies and chickens in the same way, especially since the "target areas" for trees are so large. Thus, if I have multiple valid targets it is more likely that I want the smaller/more mobile target. It can be hard enough interacting with butterflies and chickens as it is without catching them and then losing them because of hitting enter again too quickly and interacting with a tree!
Happy Easter, and thanks for a great game!
