 Here, we create a function that will increment the label after a point is added (i.e., the mouse is clicked in the viewer canvas when in the point adding mode).
 This is convenient for quickly adding all labels to a frame, as one can simply click each feature in order without having to manually swap labels.
 To achieve this, we first check if the points layer is the the adding mode (`layer.mode == 'add'`).

 Once we are happy with the annotations, we can save them to a CSV file using the builing CSV writer for the points layer.
-To do so, first, select the "Points" layer in the layer list and then click "Save Selected layer(s)"  in the "File" menu or press control+S (cmd+S on Mac OS)  to bring up the file save dialog.
