You know, i'm doing the API for advanced stripes pipes behaviors, it requires me to completely rewrite the pipe. And i stuck with one thing - on what side should it 'click'? What button it should use?(that one is easier - it use right click, but when powered it breaks blocks in front of it)
I could do more handlers(implementstion of my API) like for shears, potions and buckets - but it'll be not the most versalite system in the world.

Hmm, actully, writing more handlers is the thing to go with. This issue was about some things, like redstone, and if modders want to customize it - there is my API for them.
