Hammerspoon is awesome, I've been using it for quite some time for just few basic tasks (like move a window from one monitor to another), but those have become irreplaceable part of my desktop experience.
He man. Looks cool.. Maybe I'll extend it to just filter out any applications that have no window in the current space. Cleans up the cmd-tab list a lot
Sure, try it. It might work better than my version. I do have some other ideas for this problem (usually, i just want to fast switch between terminal and browser) but I'd like to see what other people come up with.
Recently I've made this hammerspoon "plugin": https://github.com/selectnull/hammerspoon-alttab
I would love to have feedback, if anyone is interested (it's not perfect, i'm aware of few bugs, but it solves my problem most of the time).
