Hoppers dispensing into Jukeboxes. That would be a nice feature.
Agreed! The jukeboxes also currently send a redstone signal into a comparator when a disc is inserted, but the signal doesn't stop when the disc is done. It would be nice to have a way to detect the disc being done, and a way to eject (preferably into an attached hopper) for things like disc shufflers and music loops.
Also, the name of the disc appearing when you hover over it in an item frame. (I like to show off my record collection.) You can rename the disc in an anvil, but unfortunately it loses the name when you play it, so an alternative would be to have the rename persist through that.
Mini map in vanilla would be nice--the various mini map mods seem to be a staple of many people's installations.
Teleporting in survival is already possible in vanilla via command blocks which can be used in survival once they're initially set up with commands, so since everyone always seems to have their own definition of what these "portals" should be capable of (e.g., do they work all the time, do you need a certain item to activate them, do you have to have already visited the destination once, should they play sound effects, particle effects, etc.), I'm fine with the current mechanism, as it is powerful, customizable, and easy to set up. Just open your game up to LAN to enable cheats, plonk in your command blocks and associated redstone, and close down the LAN server to go back to normal "locked" survival gameplay.
Be sure to search as well before making your suggestion, to ensure it hasn't already been suggested, and ensuring you've included as much detail as possible before posting.
Suggestions are required to be thoroughly detailed at the time of posting, and not specifically asking users to expand on a vague idea or to post separate ideas of their own. If a user has criticism or ideas concerning a developed suggestion, they will reply and you can modify your topic when it's necessary. If they have an idea of their own, they can post their own topic for it. A single thread dedicated to suggestions would defeat the purpose of the Suggestions section.
