Here is a possible new feature for Chrome OS; support for 3 more external displays.
Here is the commit:
Chrome OS: basic support for >=3 displays.
For >=3 displays always use horizontal layout and disallow mirroring.
This would allow basic multi-display functionality.
This is just a commit log on the code base for now, so don’t get your hopes high yet. I will keep an eye out for this one and let you guys know when it is added to stable channel, may be in few more weeks. If everything goes according to the plan, of course. (Not my plan btw, their plan!)
