We have some actions that require very long command line arguments (such as MSDeploy). The current "Execute Program" works but since the arguments field is a single textbox, it makes it difficult to maintain the list of arguments. The easiest way is to copy the entire field into Notepad, edit it (without the benefit of variable/property expansion), then paste it back in to the textbox.
I think it would be much easier to maintain if the arguments list were instead a multi-line textarea. When running the command, the action would concatenate all the lines, separating each with a single space.
I've attached a mockup of what the action's dialog box might look like. It's essentially the same as the current "Execute Program" action except that the arguments field has moved to its own tab and been changed into a textarea.
Thank you for your time, and thank you for making such a well-built and easy-to-use product.
