Zanzlanz, you said you can't make it so that you can left click to do stuff, but if you left click on an item in the creative inventory you get a whole stack. Maybe this year you will be able to do stuff with the left click key.
You mean the right-click key. Supporting the right-click key means dropping support for Linux and old versions of Mac. Which is a shame because Mine Blocks gives people with old computers a chance to try Minecraft :\ I'll probably do what I did for Mine Blocks 2, and release two versions of the game every update - one that supports right-click, and one that works on old computers. :)
