When viewing Opportunities in a Pipeline, it's currently not possible to view statuses you prefer. The only option is either a single status (such as "Open") or all statuses. Moving an Opportunity to a status of "Lost" means a user can't view all Opportunities except "Lost" if they choose. The user either needs to view "All" or only a single status. Lost/Abandoned statuses might not be valuable to view but Open and Won might be important to view together. How about letting the user decide which of the statuses to view at any given time with a mult-select filter?
