I looked up FastScripts and found this information from the developer/publisher about Version 3:
FastScripts is free to use with premium features disabled. The number and depth of premium features may grow over time, but as of FastScripts 3’s debut, these are the features that are considered premium, and a description of how they behave when used without a paid license:
- Keyboard shortcuts. When you invoke a script by keyboard shortcut, you will be reminded of the limitation in the free version. After dismissing the reminder, the script will proceed to run.
- Built-in scripting additions. Features such as FastScripts’s “display message” command for presenting “HUD-style” messages, the new “open web page” scripting command, and other added utilities, are all premium features. When you use one of these features, they will still work, but a dialog will appear first to remind you that they are not included in the free version.
That’s it! All of the other great features of FastScripts are completely free to use, so if you don’t miss any of the premium features, feel free to use and enjoy the app to your heart’s content!
