It might be a bit complex to pull of but as Haven 2.0 is being worked on. Would it be possible to make it handle more then the preset ingame objects. It would be nice to have a bunch of new decoration items be able to get added into the game. There could be a way for players to draw and submit sprites for objects. Maybe once every other month a pool would be made and a few items/objects would be submitted. If approved we could find more interesting vanity items in the game to just make things look nicer. The items would just be added as a way to liven up the game and make things look different from the generic bland setups we have.
Just an example would be to submit a new type of carpet, a painting or something that already exists but with a bit different look. We could see ingame items across all clients have vanity items get updated so players would be able to decorate more and give the game a bit more unique look. I'm not talking about custom graphics but a way to have the server send out the sprite and the ID of the item making it show up on all clients identically. It could be anywhere from items, world objects, clothing or portraits and some could be craftable, others could be gotten from randomization (randomly getting a different type of the same object when crafting said object) or be rarer objects gotten from extreme lucky drops.
The submitting could maybe be set so a set of items could be added quick and easy so any quantity of new vanity items could be added. Its a real shame we don't have variety of choice when it only requires a simple sprite and a bit of code tinkering to make it work.
