It kind of works - sometimes. Or I don't know how to use it or need some practice to use it :-)

I think without any visual indicator or marker it is very inconvenient to set point A and B with the same keyboard shortcut.

Please add a visual indicator and/or marker and perhaps provide three distinct keyboard shortcuts -
1. Setting Point A,
2. Setting Point B and
3. Reset and clear both points.

And consider to provide some visual feedback as soon as those keys are pressed.

For the time being I'll be using looptube.io instead.

Really lightweight and simple tool, I love it.

No instructions on how to assign a point A or point B. Uninstalled.

Just what I needed!!!

Easy to use, I love this💖

thanks Omkar Dixit

Does not work anymore.

Shortcut-keys to set A and B would be great. Works only on youtube.
