Set custom name to Areas/Editors

On very large projects requiring multiple editors at the same time (typically 1x NDA, 1x graph editor, 1x action editor and sometime 1x Dope Sheet), I often get myself lost between all those keyframes, curves etc. It would be great to add the option (maybe as a plugin) to set a custom name of our choice to editors. In fact, I think this could be useful to any types of editors. I am aware it'd pack the UI even more though, so this should probably be an optional plugin.
