Wow!!! I’ve programmed my hibernation chamber to wake me up when this PR finally merges. I did not expect to wake up as soon as 2024!!!

Please forgive my snark but I do wonder what has changed?

I’ve made multiple efforts over the years to refactor controls that had a lot of duplicated logic and same bugs reappearing across multiple controls. The argument against it was that controls are just “examples” and don’t belong to threejs core. Has this stance finally changed???

Only Controls.js has been added to core. The actual controls files remain in "examples" 😇

[arodic]

Same thing I’ve proposed years ago. Anyway, super stoked this is finally happening!

Slowly but surely!™ 😁
