I already suggested this to lemming, but right now you can make cracked bricks using the pulverizer and stone bricks.
my suggestion was to also be able to make mossy stone bricks and moss stone using the liquid transposer filled with water and normal cobblestone and stone bricks.
I also always disliked that in villages the beekeeper's apiaries were always open, while forestry has a really good smp locking function for it's machines.
I once suggested it to have those apiaries locked for players, untill you for example kill the beekeeper, or that you can only break the apiaries without it dropping anything.
I have also thought alot about vanilla enchanting, and how it's too effing random. I know of mods that allow you to pick your own enchants for free, or for a little cost, but they're just too easy for me.
so I was thinking about a tiered enchanting table. it'd start out with the normal vanilla enchanting table. nothing has changed, except you are able to feed the enchanting table xp level's through a button or something.
if you feed it 30 levels, it'll be upgraded to the next tier enchanting table, maybe also changing it's appearance a little bit. this table requires only 5 bookcases around it (I never liked having to make a whole new room just for the enchanting table and the bookcases) and you are able to get higher enchantments for your levels, even some enchantments that are normally not able to get through enchanting (like for example sharpness V) another function is that you can set the amount of levels you want to enchant from 0-10, 11-20 and 21-30 so you no longer need to constantly change the bookcases. now if you feed the table another 30 levels, you upgrade the table to the next tier, which is pretty much the last tier, with maybe also changing it's appearance.
this last tier requires no bookcases at all, gives you a really good chance for higher enchantments, you are able to choose exactly how many levels you want to spend, when enchanting books you are able to choose what type of enchantment you want (like armor or tools, because there's just so many armor enchantments that I just don't want) and a further option to choose what item enchantment you want (for tools you'd be able to choose if you'd want weapon, or tool enchantments, and with armor you'd be able to choose which armor item) but in exchange for that you'd get lower enchants for your xp levels.
and with the enchantment table I always wanted to change some things for the anvil aswell. for example when you put an item in the anvil, you'd be able to see on the anvil itself on the outside what item is in there. with this you'd also be able to leave items in the anvil. it'd be pretty awesome to have an avil standing there with a sword on it. you'd also need to have a fire nearby to heat the items, and maybe a hammer in the anvil aswell that takes damage when you repair/combine armor and tools, so you'd need to put in new hammers when they break. you'd also be able to put an enchanted item in the first slot, and an empty book in the second, and for some experience you'd be able to take an enchant from the item, and put it on the book. that way you'd be able to make an item with the enchantments you'd want (for example I never really want any knockback or disjunction on my weapons) you could also take a new anvil (with no damage) and enchant it in an enchantment table, and you'd be able to put unbreaking and efficiency on it. unbreaking would make the anvil and the hammer last longer, and with efficiency the anvil would use less experience for things. with the enchanted anvil you'd also be able to enchant iron ingots with bottles of experience (that you would make in an enchanting table) to make enchanted iron, you could then craft tools and armors with the enchanted iron like normal iron. the effect that enchanted iron gives is that it'd be able to repair itself with experience without using the anvil. you'd also be able to get experience from more things using the enchanted iron. so for example, if you kill a mob, the experience might repair your sword, if you mine your pickaxe or shovel, if you tilt the ground, your hoe and if you chop down a tree, your axe. any of these would also be able to repair your armor, but the best way to repair your armor would be to kill mobs (repairing items go before repairing armor) the enchanted iron also gives a better chance for higher enchants, and combined with unbreaking the tools and armors of enchanted iron can go for a really long time.
you will not be able to make any enchanted cobble, gold or diamond, because for me iron seems the most obvious choice for an anvil.
I also never understood why IC2 never added colored nano and quantum armor after the 1.3 update. it'd be really cool for multiplayer if you could color your nano and quantum armor, or even for singleplayer for people who like custom armor. I also thought modules for IC2 armor would be nice, but now there's already MPS so...
the BC quarry also is a bit too... simple for me. it'd be nice if it had a GUI with information in it, like power usage, efficiency, depth it's digging at, how long it's been going, how much and what it mined, and maybe also being able to set a quarry size without using land marks.
and the BC wrench, ugh, it should really take durability damage, same for the TE wrench.
well, that's it for now, gj if you've read up to this point
