Nope, doesn't ring a bell. But it's nice to see another old-school around here. :-)
I don't think I explained myself clearly enough regarding the whole brick-moving-thingy. What I want is to be able to set triggers on bricks, for instance, in order to make a door open and close. In RtB, you could do this with the wrench (and in AiO too, I'm pretty sure). You could choose whether or not the brick you hit was supposed to trigger another brick, or if it triggered itself once you touched it. You could change the numbers in the vertical, horizontal and diagonal boxes, you could pretty much make your bricks move any way you wanted. I pray to death there's some kind of add-on for this, because this feature alone made Blockland unique for me.
