Awesome!

In some files it may be javascript, in some others may actually be that our 
logic for grouping radioboxes together may be buggy. Anyway what feature do 
you want to remove? Radio buttons? Why would you do that?

If you add the feature in the feature plan[1] we have 2 weeks, hopefully that 
should be enough.
