I was wanting to suggest the time travel function. The TARDIM world (Time And Relative Dimensions In Minecraft) has commands being able to use the TARDIS to go from night or day. It would be pretty cool to have this as a singleplayer function. :)

 I agree. All the other time travel mods aren't upgraded to 1.8 anyway and 1wtc(John) could get a ton of users coming in just because of it. I would definitely would.

A lot of people don't think about this, but the things you suggest have to be Multiplayer compatible. This isn't because then the player would go to the "future" while the others are in the "past" etc etc it wouldn't work really. Plus a bunch of people on the server would be changing it to day all the time, it'd never be night.

Well, what i meant by that was like some things are disabled on the server, like the sonic blaster.

I think that this would be a very nice feature, and I would like to see it in the DM myself. I suggest having a line in the config file to toggle on/off functionality so that server owners can disable it at will, so as to avoid the concerns Arrow mentioned.
