Got few random question to ask about Multisite and related

Hi guys,

Got few random question to ask about Multisite and related plugins:

1. Is there a plugin for multisite that show Super Admin what themes are using users in multisite?

2. MU-Plugins related: If i insert custom made function.php in mu-plugins folder, it will overwrite all function of all themes with that code. This should be working fine, or am wrong? :slight_smile:

3. Got plugin in my multisite called Branding. Inside of "Branding" i got Admin CSS which i recently enabled and inserted certein CSS lines. Works like a charm in every single admin bar of every single blog. Question is, is there a way to create a css file for my themes which will do exact same things like plugins in MU-Plugins do, that means, creating one css file for all the blogs in multisite network? Is is possible and if it how? :grinning:

Thanks!
