I am in the process of customizing my GNOME Desktop for a new Ubuntu derivative I am working on.
On the panel, there is a little indicator or applet, I don't know what it's called, but I need to remove it. Here's what I'd like to remove:
Try this Gnome Extension: https://extensions.gnome.org/extension/351/icon-hider/
If you go into the settings for it you can disabling "aggregateMenu" will remove those three icons and in the next tab disabling "show extension's indicator" will remove the extension's own icon
