Good start, but...
Good for a start, but needs some improvements.
- add setting to remove examples and tutorial (or add a dropdown menu to make it less prominent; normally users only need it once).
- add setting for line thickness (per label)
- add some more colors (red!)
- add circles and squares; sometimes lines arent the best
- add size setting also per label, not only general
