Just a small improvment to combat/building and the laser rifle.
Well first and obvious,is to have a bar at the bottom of the laser rifle to see how long you can charge until release.
Now that higher level pepole also used ranged weapons a little thing could help.When in inventory you could left/right click an item (forgot which option is to chose) and add it to your weapon thingy,so when you have weapon mode you can click the arrows on the top right to switch to something like a ranged weapon (this would also be done with blocks of course)
Lastly is some sort of right click on a player to see their level weapons, items etc.Weapons would show what weapons in close combat/ranged he is using and blocks would show what blocks he has for example:
User 1 wants a telepad, User 2 says he has a telepad, User 1 isn't sure if he has one so he checks if he is lieing so he wont waste his time.
