This software is working fine for me so far:

http://www.macbartender.com

It moves your choice of (most) menubar icons (those along the extreme right edge of your main menubar) to its own sub-menu… but it’s harder to describe than it is to simply see, so visit the site.

Right now, it’s in beta, and the price is reduced 50%.

(As usual, I have no affiliation, nor way of profiting from my recommendations… just a desire to share software tools I use and enjoy myself.)
