Thank you so much! One more thing: would there be a way to check if the user has playerctl installed on their system? Or is there a Python package like it?

I like to use white on a transparent/glossy color.

Kind of like this (very old pic I know):

I feel JavaScript should be more of a backend scripting language, like with Node, than a frontend. PHP can already accomplish a lot of what JS can do, just on the server-side as opposed to client-side.

PHP+CSS is really all you need to make something feel good. People often use JS to make a site look good, yet it usually suffers in functionality.

Looks interesting. How does it compare to FreeTube on desktop?
