Today the most of people using EPiServer have screens with bigger with than the editor in EPiServer use and one thing I miss is to show the description of the propertytype on a good way.

I have made a very quick example of how it could be done, it does not look very good because it is a example made in dev toolbar on chrome, but hopefully you will get the idea of what I mean.

I do not think it should show all the time, there should be a questionmark or something that will trigger it to show.
