What if Badspot doesn't update anything because he doesn't need to update anything? Take this current topic, the hat update, does he actually need to do this update? Obvious answer is no, but maybe he isn't doing it because the community has pretty much already done hats, and the community can already do what it is asking for.
For the trading, perhaps some system like Blockland Glass will provide hat trading in the future, used in some future version of the hatmod or hats integrated into a system like Blockland Glass.
I think as long as the community has the potential to do a request to Badspot by the community, Badspot probably won't fulfill that request, so we might have to wait for something by the community to progress in order to get our hats.
