I got two things to suggest... i guess they´re pretty simple to implement:
It would be awesome if we hab something like a Billyboard or a advertising panel to place near your private or guild claim! We could write down it what we have to sell there so people can visit and trade directly. It could be a carpenters recipe! This would lead to more player interaction... what do you guys think?
A "Rotate by 90°" Button would be nice when placing objects, such as chests, wooden logs etc. If you harvest a lot of wood as a forestry man and you want to build a nice-looking stack, it would be very very very helpful.
