Missing Some Stuff

I couldn’t find out how to access my network link for multisite using this: /wp-admin/network/ it was a pain so I had to turn this off. Some other additions which would be beneficial is to turn off the drop shadow, customize the top nav separately from the side nav as my logo didn’t look the best with the colors I wanted on the side. Also to customize the color of the icons both as is and hover. These minor changes would make a huge difference in me using this plugin. Will try it out again if these changes are made available. Hello, Any update on this at all? Kind regards
