That is very correct. I propose you have make a uiListView, place an 
"Add", "Remove", "Up" and "Down" uiPushButtons next to it. When the user 
press "Add", you pop up a uiIOObjSelDlg and lets the user select items 
to be added. On "Remove" you remove them from the list. When "Up" and 
"Down" are pressed, we you move them up and down as thought above. A 
hint is that you can hook up to uiListView::selectionChanged to 
enable/disable the "Up", "Down" & "Remove" buttons. You don't want "Up" 
to be clickable if the top item is selected.

Good luck,

Kristofer
