Bug 82743 [Markers] improved problem filter needed (OR clauses)
when working with large workspaces I find the current problems filter not powerful enough. If I were able to AND and OR the conditions available from the UI then I would solve all my use cases. my most needed one is : I would like to see ERRORS anywhere in the workspace OR WARNINGS in the current selected project

return type.getLabel();
            }
            if (columnIndex == 1) {
                String superTypes = ""; 
                MarkerType[] supers = type.getSupertypes();
                for (int i = 0; i < supers.length; i++) {
                    superTypes += supers[i].getLabel();
                    if (i < supers.length - 1) {
                        superTypes += "; "; 
                    }
                }
                return superTypes;
            }
            return ""; 
        }
