We are excited to find your great library. We noticed the documentation mentions https://github.com/jasonChen1982/three.interaction.js
which is really intuitive lib, it just drops in and worked until it stopped being maintained.

We noticed that the api for three.interactive is almost identical, with one exception,
this lib requires:

interactionManager.add(cube);

With three.interaction this repeating interactionManager.add(object) call isn't necessary, so using it felt intuitive and easy throughout the application. Meanwhile three.interactive requires passing reference to the manager around everywhere and calling add() for every object? Why not make it automatically add itself just like three.interaction?
