Ripe whistle tree indicator

[ponygirl2112]

I have over 300 friends & I don't have $ to spend on this game so no daily farmer cat for me, I'd probably need 2 of them anyway, what I'd like to see is the homes with ripe whistle trees have some sort of indicator on them, heck a red dot in the upper corner or the # circle lit up would be nice, just something so that I don't have to visit every home to collect whistle trees since quite a lot of trees are bare, I think I usually harvest 136 to 158 of the 300+ trees I could harvest if every one of my friends played.
