Here's an idea: a /farm kit with a stone or iron hoe, some seeds, a block of water or two, and maybe a couple reeds or cactus.

Also, the $30 seems a little underwhelming. You can get stone tools with a mere three minutes of effort. Less actually, considering they already have a /wood kit.

Further also, I recommend that any food kit have the final products rather than the ingredients, e.g. bread instead of wheat and cooked pork instead of raw. People will likely be using it deep underground were they may not have a workbench or furnace (or the supplies/time to build one) available.

Another idea: /bookmark. A secondary warp location similar to /home, but with the intent of saving a location to return to later. I can't count the number of times I've warped out of a lucrative cavern for health reasons, only to be unable to relocate it a few minutes later. A /home2 for those with 2 or more houses would be appreciated as well.
