Hi Marc, I worked with this feature. 1. I added the "*$("#addColumns.ajax input[value=Go]").live('click')*" action to the tbl_structure.js file which gives the add columns dialog for the user. 2. Then I reused the code in "*$("#append_fields_form input[name=do_save_data]").live('click')*" action in functions.js file which was initially written for handling the table->change option. I did small changes for the same action and used with this feature. I pushed my changes to the repo. Please check that. Thank you.
