Public To-Do List for Notch

Make the server check for flying, no clip and increased speed.
Add those options to the client, but only enable if the server says it's ok.

.. or something like that

Badly needed, I'm basically using a flat file now.

Arrows, food, armor, other block types, whatever else comes up.

What's needed? What should the website support? What should be ingame?
Sort this out during beta.

Java API, fully programmable servers, for mods!

Perhaps all floating chunks of blocks should fall down, except for a special block (obsidian?) that can be used to make floating things. Floating islands would need obsidian veins to stay afloat.

Add support for small isometric images, fix the mirroring, render all entities, and don't listen to what the occlusion culler says.

Planting a flag (costs gold in survival?) claims an area of land. No monsters can spawn or die from age in that area, and only selected players can build in that area.

Would be generated by fire, be passable, cast shadows, float upwards and disappear after a short time.

Same as Survival Mode, except you can't craft or modify the world. Used to play missions on pre-made maps.

Mix water and different ingredients to make dye. Apply dye to cloth to color it, or to signs to write text.

eg lava + sand = glass, lava+water = stone (already in, but not generic), water + crops = watered crops, or whatever else.
