It would be nice if there were an option to run the game in fullscreen (IE it covers your whole screen, not just maximized) I get sick of running the game in a higher resolution, and being left with a huge ugly grey part at the bottom of my screen T_T
Also, maybe more menus with buttons that cover commands, with confirmation messages for the more important ones such as buying/unclaiming land, so it makes it easier for new people to know what to do (I have known quite a few people who quit because they hated asking for commands all the time, and couldnt remember them /sigh)
Oh wait, another thing. I made an appeal on one of the servers over a year ago which never got answered -
Allowing a player to give someone rights to specific square(s) on your land, so if you were letting a player freeload with you, it would be possible to give them their own little space and not worry about them poking through all of your chests.
