i have a few ideas one is a trash can if you dont want an item while holding this item right click on the trash can a menu will pop up saying cancle if you accidently clicked on it and how many of that item you want to throw away!  the lava trash can things could burn down your house and throwing them in water you can accidently step on them again and get them all back and how annoying would that be am i right!  another idea is money i know sometimes it will get annoying and make you mad but in multiplayer if you open a restraunt odds are your gunna get robbed and not gunna have any food left!  if you have money then you once at a store or restraunt if you pick an item up unless you put it back the door to the restraunt will not open until you pay and if i guy doesnt pay but another guy does the door will only open for him not the guy who didnt pay!  and i know your all wondering how the hell do we get money well i was thinking that when you grow crops when they are done growing you right click with them in your hand ( make sure your not right clicking on another item that uses the right click button) and depending on how big the crop is you will get a price another way is getting a job you can work in a restraunt,store, as a builder, in a hotel, a tour guide, and an engineer. ( if your having trouble wiring something with redstone or something like that call an engineer with your celll phone one of my creations i will tell you about in a sec)  the enginner is an expert on redstone and will help and susceed with you!  I didnt know if i should have said this but you can also become a teacher but whats there to teach like how to mine how to build engineering all the basics but you could just look on wiki for that!  the cell phone idea isto call one of the people working in a job like a store to see whats on sale a restraunt person to order take out or to know there specials like i said before the enginner to help you with redstone the builder to build you a knew house a hotel to check in and a tour if your knew to the place!  thanks for reading if you read!   please comment below if you liked my ideas and i want to hear some of your ideas
