  Hallo,

  it is possible to create a marker database by script and show the marker browser dialog with that marker database.

  I have added a sample script that demonstrates how to create, fill and show a marker database. In that script the database is filled from the shapes on the currently selected layer.

  Best regards,

  Matthias

    app = RBA::Application.instance
    mw = app.main_window
    view = mw.current_view

    return unless layers.size > 0
  
    cv_index = -1
    view.selected_layers.each do |l|
      if cv_index >= 0 
        if l.current.source_cellview(true) >= 0 && cv_index != l.current.source_cellview(true)
          raise "Selected layers must originate from the same layout"
        end
