so I can access the script on multiple computers and if I make changes on one computer they sync to any other computer I use.
I use Alfred on mac, which can sync the shortcuts (workflows) using Dropbox.You can also use a 3rd party app to set a shortcut for the script. You can then give it a shortcut in Edit > Keyboard shortcuts. You can put the script in the 'Photoshop/Scripts' folder and it will appear in the top menu File > Scripts > SaveTo after a restart. It got a bit ranty after the first bullet point so if you only want to run the script not worry about details. How to install the script/set the shortcut: Tip: When you simply want to save the files without changing the filename or filepath, you can just trigger the script and then press enter once for each dialog (2x). I also added the code to the bottom of this post.So I have this script that I use to easily save the work file with the production file in Photoshop and Illustrator.
This doesn't fully answer the question, but you wanted me to post this, so here we are.
