Open Embedded scripts with a external editor like ISE PowerShell.
It would be nice if you can conforably open the Embeded scripts in a Editor of your choice (like "Open with..."), so that you get the code specific Syntax and coloration and can view the Special caracters like carriage returns (which can mess with the process). For example you could open the pwershell script in the ISE PowerShell Editor.
I could imagine something like EM provides a temporary file out of the embedded script data and starts the file with the "Open with..." option. After editing it in the prefered Editor you save it again in that temporary file. And when you go back to EM you could refresh the changes back in to EM with one click.
