Workspaces are an amazing new way to manage your windows an applications.
With conventional window managers, your windows are just grouped by application, or even not at all. Suppose you're writing an article, and you open up a web browser with some reference material. You open up your mail client and open a PDF attachment which a colleague thought might be helpful to you. Then you put on some music and start writing. But now you're switching back and forth through all the webpages you have open until you reach the one you want, past the mail client and the music player and the PDF back to the document you're writing. Things like this are a big problem, but thankfully, that's the old way.
With Workspaces, we offer you an awesome and new way to organize yourself. So you're ready to start writing that article again - you open the word processor. We're all familar with that, but what happens next is where the incredible new power of Workspaces is shown: press ctrl-alt-2 to switch to a second Workspace where you can open the browser of reference material. That's just amazing!
But that's not all. Next, you can press ctrl-alt-3 and open your mail client, and it opens in yet another workspace. We can open the colleague's email attachment and press ctrl-alt-shift-left to move it to the previous workspace, where we can arrange it side by side with the web browser window. Now what's awesome and incredible about that is you can flip between your word processor and the reference material with the keyboard shortcuts, without having to sort through windows ever. Amazing!
Oh, but before you start, you want your tunes again. Ctrl-alt-4, open your music player, ctrl-alt-1 back to the word processor. Awesome!
Workspaces. It really is just that simple.
