I am a recent farmer and find something new everyday.
When I visit a neighbors farm and click on a tree that I wish to harvest I find that sometimes , even after clicking on the tree I still don't get the product I wanted. My friends who introduced me to the game , have been playing for over a year. They too faced the same problem.
For example : I needed 5 cherries and the person has 5 cherry trees. Is it possible to allow on the first visit, to harvest all the 5 cherries from the trees, at the neighbors farm, on the same day? - Get 5 cherries on same thevisit from 5 cherry trees
Another suggestion is to know whether a neighbor ( my friends on facebook ) can trade products with me if they have the product in their barn.
This will make it participatory, interactive and proactive to make farming lucrative and extremely thought provoking . These ideas at the game level can make the actual ground level farmers so much more communicative and progressive too !!!
