If Netmo does not appear in the menu bar, please check the 'Menu Bar' section within the macOS System Settings to ensure the app is enabled for display.
Since Netmo is a dedicated Menu Bar app, it doesn't use a Dock icon. To access your data or the login screen, just click the Netmo icon at the top of your screen.
Maybe you can hide some menubar items on the right side, like the Bluetooth symbol or turn on the symbol for the fast user switching and not the full name. You do this usually in the system settings of macOS.
Another solution is move Netmo to another position. Just press and hold CMD on your keyboard and move Netmo with your mouse/trackpad (btw, this works with every menubar app).
