Does the form script still allow Visual Studio to edit, save, and compile in Cloud?
Yes, that is still possible in the Webclient (no difference between on-prem and cloud) although not quite as comfortably as it has been with the WinStudio client.
You download the FormScript as a project which you can then edit locally and upload the script back up to the cloud.

Thanks. I'll give it a try.
