Menubar icons being cut off
Since Apple does not provide tools, I would suggest the Bartender app to organize your menu bar.

Organize your menu bar apps

    Lets you tidy your menu bar apps how you want.
    See your menu bar apps when you want.
    Hide the apps you need to run, but do not need to see.
    Have the clean looking menu bar you want.
    Rearrange your menu bar items as you wish.
