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 Vertical monitor orientation snap area bug
The snap feature currently is not working on monitors with vertical orientation. The snap areas show up, but the window never snaps in place. You have to manually adjust each window on the vertical orientation monitor.
Con Costs
BetterSnapTool is no longer free and now costs $3.
