The little differences to the "real" Material Design are giving the kit some character. Thought I don't like the border on the switches and sliders this is a good kit. Well done!
@Alexander thank you for the feedback! I'm one of the creators of this UI Kit. I understand your point, we wanted to make it a little bit different than the regular Material Design, that's why we change the default switches and sliders. The default switches are some kind of "too flat", just a personal feeling :D
IMO the ripple effect does not seem fluid, surely an ease-out easing would be more appropriate for showing immediate touch feedback?
@marco, thank you for the feedback. Can you please tell us on which device/OS you tested the ripples? We want to check them and make sure they are fluid as they should be.
I mean, it is not really a performance issue - currently the kit uses an ease-in easing where it starts slow and gradually gets faster throughout the ripple animation, but since the purpose of the animation is to show to the user that their touch has been acknowledged, I would think an ease-out easing would be better in this context which has much more immediate results.
From design.google.com, it seems this easing function is also suggested by Google for these purposes, as seen in the example videos.
Now I got it, yes you're right. We will check your solution to see how it is working. Thank you again for the great feedback! :D
