I know we already have some - the Mayor's House, the Barracks and the Provision House, but it would be really useful to have more.
Specifically, I'm thinking of the other buildings that get visited as often - the Elite Barracks and Rarity Provision House. Could I suggest E and R respectively?
I realise this will be a little more tricky because they are non ubiquitous buildings, but it should be possible to implement it so that it checks for the presence before trying to launch the interface.
Cheers
