earlier idea for moi, realization in blender -> intuitive
moi doesn't have pie menu, but it could have some after shortcuts, s for align, and s + w -> top , s + d -> right, s +a -> left, s + s -> down
ps: i wans't in blender when i've posted
in blender it's must to have for hard surface, anyway up to scripting moi's "point's scriptable" won't be reason to implement
