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

button = createRadioButton(parent, Messages
                    .getString("filtersDialog.noWorkingSet"));

            button.setLayoutData(data);
            Composite composite = new Composite(parent, SWT.NONE);
            composite.setFont(parent.getFont());
            GridLayout layout = new GridLayout();

            layout.marginHeight = 0;
            radio.dispose();
