Hi Guys,
I posted about Afloat some time ago. At the time I found it to be an extremely useful utility, especially when working on a single monitor as it 'floated' apps that you need on top.

Recent Mac OS upgrades made Afloat installation impossible but with High Sierra its possible again.
I discovered great step by step instructions by Damian, here, https://www.maketecheasier.com/mac-keeping-your-application-window-always-on-top/
If you install Afloat don't forget to re-enable System Integrity Protection.
