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

        combo.addSelectionListener(selectionListener);
        return combo;
    }
    /**
     * Method declared on Dialog.

    protected Control createDialogArea(Composite parent) {
        Composite composite = (Composite) super.createDialogArea(parent);
        
        createOnOffArea(composite);

    protected void createSeparatorLine(Composite parent) {
        
        Label separator = new Label(parent, SWT.HORIZONTAL | SWT.SEPARATOR);
        GridData gd = new GridData(GridData.FILL_HORIZONTAL);
        gd.horizontalSpan = 1;
