A undistupably good idea.
 

Have it so when you click on an item and it shows shows it in the top right of the menu, there are options. Equip, examine, drop etc. It is annoying having show much text at the side when you equip items and the double click to equip can be annoying as well.

That would be much better... double clicking is a pain.

and maybe like a /drink # water command so you don't hvw to clcik it 1000 times

Is there a way of assigning certain equipment to hotkeys? Like assign #1 to your Diamond Sword, and then press 1 to pull it out automatically. 'Cause when I'm standing around growing corn, and people come walking up, I hate having to switch back and forth between the water can (to grow corn with) and the sword (to defend against PKers, if they attack).

the command is either wield or equip.. whichever it is:
/bind /whatever Diamond Sword 1

I tried both of those, and some other things... nothing worked. :(

I wish there was a better way of learning commands than just typing /help in the game... that doesn't explain much of anything.
