Thanks - it does help. So now I have a better understanding what it does - if I were to express my understanding in a single sentence, it would be something like "Mjolnir allows you to script Apple mouse events or system dialogs in Lua and assign them to a hotkey - no need to use Apple C API".

Again, if you target Mac power users (which is the right market you should probably target - much bigger than just developers), I would emphasize higher-level stuff you can do with Mjolnir and ease of use comparing to AppleScript.

For some inspiration, go to App Store and search for "Automator" - you'll see several bundles that help people automate programs like Adobe Illustrator, etc.

Just my 2 cents. Good luck!
