It is more than flexible and writing and debugging takes more time than writing a question on the form and search for tullinge.
Standard solutions quickly become complicated if they are not oversaturate requested feature. Full screen mode in osx is the new desktop, if you try to roll - you will see nothing except your screen saver, learn to operate on desktops is much easier and more productive than minimize Windows to the dock.

Convenient multiple desktops on each monitor, and swiping three fingers between them.
