Show HN: Instant macOS space and app switcher

https://github.com/theo-sardin/instant-switcher
1•elar_verole•3h ago
Hello HN,

I want to share a small wrapper I built around https://news.ycombinator.com/item?id=47708818.

The idea is to allow instant switching between fullscreen apps / desktops, with the ability to register shortcuts to instantly jump to your favorite apps, without animations.

To be clear most of the hard work was done here: https://github.com/jurplel/InstantSpaceSwitcher, this is just a wrapper to build custom shortcuts around this solution, Ala Apptivate.

This is mostly vibe coded, but took me a bit of time to get right and is really useful for my workflow, and I know it's a very common pain point for Mac tech users, so thought I would share.
