In a list of stocks being viewed in Folio screens, I think it would be a great help to remove stocks not being reviewed. The side checkboxes let you select stocks for deleting or viewing in the compare mode. Why not add a Focus option that hides listing stocks not selected so that you can page through customised folio views such as Value, Quality, etc and see just the companies you are actually presently interested in?
A Focus button would show only the companies currently selected with checkboxes in Folio pages.
