When maintaining list based forms, which tables are affected? I see layout\_options,&nbsp; and lbf\_data, I also see that a row gets created in list\_options for the new form, but I am not sure what table stores the groups?  
I would like to figure this out so I can add this info to the documentation on lbf.

Layout items including their group names are stored in layout\_options.&nbsp; list\_options is affected only in that it includes a list of the layout-based forms; and of course layout items may reference lists that already exist.
