Add option to launch and debug external powershell.exe

[clmcgrath]

Now that we have an attach option it would be really helpful to be able to
automate this process into an launch external console option

theoretically could this not simply be done by creating the powershell exe in a windowed mode then adding the attach functionality to add the debugger

the built in debugger is great but we lose all layer 2 interactive functionality like progress bars and message color

Certainly a possibility. We could launch powershell.exe to run a specific script and then auto-attach to it with the debugger.

I would love to see this feature!
Coming from PowerGUI, I was very fond of the "Run in External PowerShell Window" and the Script Parameter input options.
Running externally eliminated the weird ISE-style issues, allowing me to see exactly what the end-user would see.
Allowing for Parameter input allowed me to see exactly how the script would handle itself when passed a simple string. Very neat.
