I think a fantastic idea would to be able to buy or make a greenhouse area that has a certain number of plots either herb or crop, so in your houses with herb plots you can grow crops and vice versa.
You should be able to mine ice chunks in the Wintry Place to make drinks with. For us lushes out there.
Also, since Glitchs don't seem to have the proper respect for the wood tree, it would be nice to see the planks used for more things and perhaps to have an "Arbor Day" where you get an achievement for planting a wood tree (or more)!
Thoughts?
