I would like to see:

A better way for healers to gain skill than in VV4. I find it practically impossible to get a healer to master level because the villagers almost never get sick. So tryiing to get a scholar or even multiples is next to impossible. (Maybe I am doing something wrong.) In a previous VV I would just keep taking them around to plants to learn but in VV4 that doesn't work well.

Rather than getting rid of the parrots or some other animals I always wanted to tame them and let them become pets for the kids and/or adults.
