Video Scrub Prototype
I find the video scrubber hard to use on mobile. The scrubber dot / timeline approach to show video progress is obviously a remnant of the desktop world when the cursor afforded much more precision.
But on mobile these dots are tiny! If I want to jump to another part of the video by tapping, most times my finger couldn't even land on the tiny progress bar on the first try.
Apps like SoundCloud already solved this by relying on drag, a mobile friendly interaction to scrub music. I think it can also be done for video.
