Hey! Thanks for the handy lib. Perhaps have the option of passing in a function to the easing prop? One could then import default easing functions (say an easeInOut / spring fn exported by animate-value) and apply it as needed, or be able to pass in a user defined fn.

I like this idea, not a difficult thing to implement I guess.

It would have to be an easing functions that returns a value between 0 - 1

[kavsingh]

For sure. I guess it would just receive current time as an argument?

[geoffreydhuyvetters]

value between 0-1 which recalculates it via easing to 0-1

PR always welcome btw :)
