I implied that it will be in the next version 4.0.0 :)

We have already a remake of this feature, in our deveporer version (in github)

Do you like it?

You are doing nothing wrong, the file is just missing from the server :p , Sorry ^_^

Anyway, v3.3.0 has just some features disabled (they through errors), you will not gain sth upgrading.

You can get the latest build (v4.0.0) at its current state, from github:
