I've been thinking about what features to add to PlainDAQ's GUI.

Here is one of them: Movable/Interactive Vertical cursors for viewing real-time statistical data.

Simply by using middle mouse button and dragging it while holding the middle button you can place veritcal cursors. You can analyze the data in between the cursors.

Some people said that it's very wierd to use middle mouse button for that purpose. What are your thoughts?
