Hiiiii guys, i’m completely noob and i want to ask something.

First of all, sorry for my english.
I’m not that good at english lol.

I have a question about configuration of my mirror.
I want to hide all of my module on my mirror screen. i know how to hide each module with < module.hide() > this function.

But what i want to know, it is how to hide all my module right after i turn on my mirror.
Like, when i turn on my mirror with < npm start > there must be nothing on my screen. except assistant or hotword. and after i call each module, i want them to appear.
Is there any way to do this?

and second, is there anyone who use < MMM-Youtube > module?
this one -> https://github.com/eouia/MMM-YouTube
I want to use this module with hotword but i don’t know how to use this at all.
Of course i read document and read.md blablabla but i don’t get it…
Anyways, if you use this module, please give me some example how to use this module.

Have a nice day!

Thank you
