OMG. If we could group multiple items while designing levels, it would be so much easier to move sets of items around WITHOUT having to select them all (especially if you're shifting Block creations).
In fact, could there be a way to make grouped items a single entity? (This could make it much easier to tag many things together, when dealing with triggers.) (This may even make it easier to create custom sprites with less coloring restrictions, PLUS maybe overlapping Blocks of different shapes could be grouped.)
Thinking of how level codes work in LL, this, however, might be tricky to work... especially the layering...
