Don't use the wand, get something like the macro mod and bind //hpos1 and //hpos2 or learn to use //expand.
Also, I have a suggestion for #1: Instead of everything being commands, you should implement some kind of CVar system. It would remove a lot of command clutter, and allow the creation of multiple executable Quake-like configs.
At this stage in post beta the developers could simply quite obfuscating the code. That would make all mods quicker and easier to develope... of course I only know what that means because a post long ago by simo.
if you dont like it the short and sweet is to delete your bin directory for the game.
c:// ---> users ---> (whichever user you installed MC on) ----> appdata ---> roaming ---> .mincraft ---> Bin (delete the whole folder)
After you do this log back in to the game and you will start downloading another bin that has not been messed with. This will not effect any zones that you have played thus far it will only delete any mod you have ever installed.
This is the downide of the easy installer. Unless you have been adding mods to your game for a long time you don't know where the directories are...
Another thought. Before installing mods in the future I would recomend reading all of the authors first post at the least. Then you will know if it will alter the game in some way you don't like. Also, you may want to consider youtubing videos of any mod before use so you can see it in action to validate that is what you want.
My personal thoughts on a game entirely designed to be modified by its users is this. Tools that are developed for a completely mod open game are no different than me using a pneumatic nail gun to build a house while you run around with a hammer.
both are effective tools and we each have preferences good or bad, but they are tools just the same. In this game they are tools not cheats. If you prefer think of it like this. Most of the users of this mod will have exhausted their individual entertainment of the raw game. This mod allows for another dynamic to the game. It also allows creative mode players to accomplish builds much faster. It allows you to spawn rediculous amounts of enemies for a modified suicide run...
For instance a modified suicide run. Use this mod to add every enchant at max to your diamond armor and weapons. Then build a massive room and install spawners of every type by the dozen. Load the game without turning off damage and see how long you last.
Anyway the point is it is just another way to enjoy the game with a pneumatic nailgun rather than a hammer alone.
