Why??? You can create and use 16 work spaces with Linux, I've found that 5 is my maximum, any more gets confusing in my senior mind. When all 5 are on the screen it looks like a collage that defies logic and is useless, even for a 17" screen.
What I like better and is more useful to me is to create a 'hierarchy menu' in your browser. You can create one in either Firefox, Chrome or MS's browser. I only assume you can also create one in 'Safari', don't know. Works great for me.
You can nest a list of bookmarks to show a relationship among topics and sections. Nested bookmarks with a parent/child relationship. You can expand or collapse these nested bookmarks to switch among different page views.
