I haven't used checkLISTs much, but they would not work in many areas where I use checkboxes. For instance I will put 5 checkboxes next to an item in a monthly todo list that I want to do weekly.
I too have a mish mash of check boxes that have been converted to checkLISTs. At least stop the automatic formatting. If I have inserted a checkBOX I want it to stay a checkBOX.
I'm there are good uses for checkLISTs, but they should coexist peacefully with checkBOXes
