An interesting post was recently put up on CyanogenMod’s Google+ page. In it, Sven Dawitz discusses the use of OnSkreen’s recently open-sourced window manager – Cornerstone. The plan is to integrate it into the tablet version of CM9.
At the current stage, it’s just in testing, but there are some shots that prove it works. CM says:
We should clarify; this is experimental, and not guaranteed to be mainlined into CM. If it is done, it needs to be done right and not break apps all over the market or be a nightmare to upkeep down the line.
So, we could theoretically see it if all goes well. Obviously the software is of most use on tablets, where the extra screen space affords the use of more windows. A multi-paned approach is being taken by Microsoft in Windows 8’s Metro interface, and the addition of it to Android may boost the utility of Android tablets quite significantly.
