I have a suggestion for possible item that someone might be interested in creating...flags.
The in-game flags are poorly designed, with an arm dropping down to hold the fabric straight, and the are just ugly flat planes. Especially ugly when they are used as a traditional flah flying from a vertical pole.
Would love to see a more natural looking flag, without that extra arm, both as a flag flying from a vertical pole as well as one hanging from an angled pole attached to a building. They wouldn't have to be animated (although that would be cool...), if they were static they could even be billboards if they some day allow us to do that. Once the initial model is done, it should be a simple switching of the texture for the flag design to allow many different national and other flags...
