To hide modules you probably could use MMM-Remote-Control:

I don’t have any experience with YouTube module, though

Dear @Babene1 ,

thanks for your quick response. I use the same module and since the module is working for you I was wondering what else could be the error. And I have found a solution: the latest module I installed was MMM-GoogleMapsTraffic. I deactivated that module and now MMM-mvgmunich
is working again. Vielen Dank!

Hey all,
I have been using MMM-mvgmunich on my mirror but since a couple of days the cool module is not working anymore. Do you have an idea which similar working module I could use to show public transportation times in Munich, Germany? Thanks!

German/Deutsch:
Hallo alle,
ich habe auf meinem Spiegel MMM-mvgmunich integriert, aber leider funktioniert das Modul seit einigen Tagen nicht mehr. Kennt jemand Alternativen, wie ich mir die Abfahrtszeiten der MVG München anzeigen lassen kann? Danke!

@rmonteroc
I am using this module on my mirror. It is working fine and is a little bit newer:

@costascontis
Are you using the digital or analog displayType?
There is a setting for the analogSize where you can use a number as pixel size

@Fulcrum1973
Have you configured the units in your config.js?

I integrated two new modules into my MagicMirror:

• MMM-GoogleFit

• MMM-GoogleFit

Meinem MagicMirror habe ich zwei neue Module hinzugefügt: Tägliche Schrittanzahl meiner Garmin Fitness Watch und Körpergewicht, synchronisiert über Google Fit. Dazu eine Google Map meiner Umgebung inklusive aktueller Stauanzeige.

I am a total beginner and just searched the forum and found this solution. There might be a better way for you since I use a special set of icons

@Stoffbeuteluwe
I changed the icons to new ones via css

Get rid of "pages": {"Video": "bottom_left"}and try that:

{
    		module: "MMM-Remote-Control",
			position: "bottom_left",
			config: {
        			customMenu: "custom_menu.example.json", // Optional, See "Custom Menu Items" below
    				}
		},
