Just a small consideration, is the picker example still up to date after these changes? I assume that it is but just in case 🙂

Good point - I also included in the docs the fact that a user could now just say design.plot(allow_picking=True) if they wanted. Also, the example was working fine buuuut... only for Windows. The Linux service was crashing since it does not allow for multiple designs, so I had to change the location of the multi_colors section. Thanks @AlejandroFernandezLuces for the review!
