What would you like for the next minecraft update?

Hey guys, I was wondering what you would want Mojang to add in the next minecraft update! I know 1.7.2 just came out for PC with stained glass and carpets and such, but I really want them to add some sort of a block that can store power from furnaces and daylight sensors and use it whenever you need it, like storing solar power during the day and using it to power redstone lamps. I know there are mods and things like that for this, but for security reasons, I do not download these from untrusted sites. That only leaves the updates, which only come out like once a month. So, what do you guys think?

"You must have command and conquer 3 tiberium wars installed to play kanes wrath

Hey guys, unfortunately I have a problem with command and conquer 3 kanes wrath. If you have been having this problem and know how to fix it, definitely be sure to let me know in the comments. So heres what happened: I bought the command and conquer ultimate collection on origin and downloaded command and conquer 3 tiberium wars and kanes wrath, and when I started it up, it worked perfectly fine, and it did about the first 10-15 times I launched it. Then, one day, I tried to open kanes wrath in origin, and an alert came up saying: "you must have command and conquer 3 tiberium wars installed to play kanes wrath". But I already DID install tiberium wars. I have no idea what has happened to it, but after looking at other posts about this same issue, I was able to determine that kanes wrath was unable to detect that tiberium wars was even on my computer. So does anybody have a fix for this? If you do, *PLEASE* let me know, because I really wanna play global conquest!!! :(
