Seconding the pickaxe repair suggestions. Some way to create them would be nice too, but it’s a little ridiculous to just toss a tool the instant it breaks.
And yes, please either link the fabrication bays or at least put an exclamation point on both the map and the screen over the bay so it’s easy to tell where to go! As for the item storage-dealing with other people’s fabrication, what about a Mine/All/Friends/Contributed To kind of button (like chat channels)? The last one showing any project that you have contributed resources to. That should definitely default to Mine, too (or default there and then let you change Default in a menu), otherwise it’s going to be a confusing pain.
Also, PLEASE increase speaking distance! I can’t talk to someone who is effectively three feet away from me.
