Hello naparistas!
In recent months, core dev @czaki has been hard at work to improve the performance of our Shapes layer. We've now released napari 0.5.6rc0 with the option to turn on C++ acceleration of Shapes layer creation. If you use the Shapes layer please help us with testing! Check out our ✨brand new blog✨ for all the details!
