The house requests are definitely welcome, although probably won't add much more house-wise yet. I need to really think through ALL possible house additions and make sure the system is modular enough so that I don't have to redo settings or image data every time we add something.
Some kind of twinkly thing on the Gardens tab when I have rewards to collect would be nice. Or maybe (preferably) a little notification on the screen when I've completed a quest. As it is I don't really know when I've completed a quest, and a little message would be good for the dopamine hit. :)
Edit: Like the little popup that comes up when I complete a daily challenge. Unless it's appearing somewhere and I just can't see it.
Not an item request, but one thing which would make the quests more impactful for me is if I could quickly see which quests I am getting close to completing. A toggle to sort quests by % complete (highest to lowest) would provide this functionality.
