A few things in the SMEdit I\'ve witnessed that would be nice to get fixed/implemented (if these already exist, my apologies):
Features:
Center view. When working on large ships, it becomes very difficult to reset the view to be looking straight down the middle. A reset view could be handy, especially given the sensitivity of the current rotate.
A way to select all type and remove them... in my case, select all wedges and delete. (when I scale up by 3, all wedges become a 3x3x3 block of wedges)
Scale should have a means of maintaining symmetry for a ship built with the core as the center (perhaps a checkbox or something). Currently, if I scale a ship up by 3, the core will appear, not centered, but at the corner of where the one square became a 3x3 square (IE, it\'s off center by 1 square). Furthermore, for some reason, there will be one row that will be composed of only 2 squares, not 3 as it should be. You can see this, even on the default pirate ship. The reflect tool does not fix this, it only reverses which side the oddity is on.
