I wouldn't like them to change the system of 20 hour days now that we are all used to, but I'd love them to add a few crops at the top end that are 5/6 farmtown day crops so that we could go away for a 'real world - 24 hour day' week and come back knowing that our crops are still there waiting for us.
Currently, if we go away for a full 7 day week (ie: Sat am - Sat pm the next week) the four day farm town crops don't quite make the distance
I take a small netbook computer with me, but sometimes we farm town addicts are forced to give it a rest
