Install SeeYou on Mac
You can install SeeYou.Cloud as an app on your desktop. Doing that will give you more screen for the map than running it in a browser window and it will give you an app icon you can start from your desktop.
On your Mac it is as easy as running Chrome (or any compatible) browser, clicking on the three dots for settings and choosing "Install SeeYou Cloud":
That's it! You get an icon in your taskbar. Good to go!
