I often use linux and love the possiblity to use tiling window managers in this context. These window managers are extremely productive once you get used to the paradigm. 

Tiles already adds some of the features to a windows desktop but it lacks a few things for me:

- Keyboard shortcuts to switch to a specific page (more then "next" and "previous"). How about Win+Number? I know it's being used by the explorer but maybe these can be rebound? Or some kind of overlay menu can be added. 

- Shortcuts to move a window to a specific page. (Shift+Win+Number) 

- How about a "page of pages"? A page which shows a preview of all other pages/desktops could be useful to quickly find something.
