We want to adapt the way quotations (sales order) are edited. We want to add a number of fields for our own administration. Problem is that the tree view containing the order lines gets too wide. What are options of stashing away some of these fields (i.e. columns) in pop-ups that open one you click a field? Or is the only option to make that list contain only read-only but clickable rows that, when clicked or a new row is added, opens a complete form showing all the fields for that line?
