  33 // To do:
  34 // - More context menu items
  35 //   - Don't select on right click
  36 // - Player
  37 // - Add a screenshot to the user's guide
  38 // - Add filter for quickly searching through list?
  39
  40 // Bugs:
  41 // - Preparing a filter overwrites the existing filter. The GTK+ UI appends.
  42 //   We'll probably have to add an "append" parameter to MainWindow::filterPackets.
