Aaa, you saved me, thought it's broken, but you have to drag this thing!

ps. video shouldn't loop as default, it's annoying.

I actually like the default looping. When I’m learning and trying to train my ear, I need to listen to the phrase over and over and it’s helpful to not have to click play again.

You didn’t even read the most basic settings that clearly say “click and drag interface” or something similar. But I still agree, tapping/clicking should work in sequential order eventually (it’s not as easy to implement).

Re, looping; there are controls to turn it off. You aren’t paying attention one bit. If you’re going to say things, at least be diligent in the things you are going to address.
