Hello,
The Sonos apps do work properly for sure but I have just a UX question : do you think you can design something even smaller??? :-))
For example the seek slider on the desktop app for Mac
This gives the feeling that the very tip of the mouse pointer must be at the exact pixel where the slider bar is. This is not the case actually but still.
The buttons next to it are bigger but not big either.
Looks like you’re shy :)
Make huge buttons and sliders! Don’t hesitate. Think UX and accessibility.
The same applies on the mobile app (even worse for seeking).
Thanks
