aliciaviola - There is a feature in MC on the Mac platform that does not exist on MC on the Windows Platform which with a bit of Manual Help makes incorporating some of that New Sequoia Only Feature a bit unnecessary.
To find out what this mysterious feature is with MC open, I tried it with the MC window occupying the whole of the screen between the Apple Header bar and the dock, click on the MC windows maximise button and you should spot that MC is doing the opposite off what you would expect it to do; because the MC Window will shrink to about 1/3rd of it's original size.
You can then use the handles/tools to move it anywhere on the screen as well as make it any size you like; Now for the fun/interesting bit, not only will MC remember how big that "smaller" window was it will also remember where it was positioned on the screen. When you want to get back to the Normal/Usual sized window all you have to do is click on the smaller MC Windows maximise button.
