Pro Automate actions based on the operating system
Hammerspoon lets you hook into OS level events and trigger any action you can imagine. From setting up a simple keyboard shortcut to launching a complex workflow using multiple apps and scripts.
Pro Convenient and fast access to files and notes
Unclutter lives in the navbar at the top of your screen, and is always accessible. Any files and notes stored in Unclutter can be quickly accessed from anywhere, with just a mouse movement and scrolling down.
Pro Keep desktop clean(er)
Instead of keeping commonly used files on the desktop, you can tuck them away to the top of the screen. This can unclutter your screen, or create more room for more icons if you like quick access to everything.
Cons
Con Has 324 issues on their download page in GitHub
https://github.com/Hammerspoon/hammerspoon/issues
I can not list all the issues.
Con Some knowledge of programming required
Hammerspoon is scripted in the Lua programming language, and some familiarity with programming in general will be needed to use it. Some plugins exist that can be used by adding some files to a specific folder, but this will not give the flexibility that is so key to Hammerspoon
Con Can't keep visor open when typing in other applications
The unclutter visor will not stay open when working/typing in other apps. Sometimes it is desirable to use the visor to re-type things, it's not possible outside of copying and pasting, or opening and re-closing the visor.
Con $10 seems a bit much for what it does
