On the Portfolio view screen, you have the "Show" drop down box, then the "Group By" drop down box. How about a third drop down box and have the class and type (or more) in a drop down. With the second sort, we can have the "Value" screen, then sort by "Accounts", and then sort that by "Type, Class" or what ever else. This way you can sort out the types or class seperated and listed in each account. And make so that we can move the types and class or others up and down.
PS In Microsoft Access you can have two different sorts.
