Hello!  I love this tool, and wondered if you would consider something for future development (if it's even feasible).  I would love the option to split and/or merge cells,  as well as to add/delete handle points from cells.   I like buildings to appear tightly along roads with a minimum off odd shapes so that the roads look well-defined, and being able to manipulate the cells more than just by dragging exiting handle points would give you much finer control.  Just a thought/wish.  Thanks for the tool, in whatever form it takes!
