Change width of both Bootstrap columns on edit/insert page as an option?

Would it be possible to add an option to the config file to set the width of the column with the label and the column with the actual field?

Currently they are col-sm-3 and col-sm-9, respectively. Personally I keep my database field names short and I need a lot of width for the fields as I mostly use it for editing html with the rich text editor.

I changed lines 19957 & 19963 and 20405 & 20411 in the grocery-crud-v2.9.3.js file to change the colomn widths to 1 and 11.

This works perfectly but only until there is an update, obviously. It would be really nice if in future this could be set via config.php.

Thanks!
