Backend customizations.

It would be nice if we could customize the dashboard and content via the backend. I for one would like the ability to add in my own links and content without having to customize files directly. Having something like this would be great, especially if the customizations were save directly via separate files and ES called those files. That way if there is an update it wouldn't remove the customizations. It would simply recall the files after the the update was installed. I also think this would make it easier for other software developers to integrate thier software with very little effort.
