I have a lot of other things on my plate at the moment and not a lot of time, I'm struggling to even find time to work on C&B it self, let alone another mod / add-on.
I also don't plan on merging it with C&B, its tools are neat, and helpful, but they also work quite a bit different than C&B itself. Which is fine, but it means it makes sense that it would stay an add-on.
I don't know weather Phylogeny plans on updating or not, and haven't heard from them in some time.
I just checked his curse and i see that he has updated his mod to 1.9.4, BUT its in beta... the one below 1.9.4 is a release (not beta).
