Duly noted. Keen to add those, let's see if the proposal gets through this time.

By the way, I was looking into your PHP Hive Tools and I couldn't find a code for Hive signing.

I'm looking for it for a Hive signing step-by-step procedure for serializing and signing for couple days now from the traditional places(Google, Stackoverflow, developers.hive.io, etc).

If you know a place where I could find those, I would appreciate it.

As far as I know, there aren't any PHP implementations for serializing / signing a transaction (this is part of my development roadmap for this proposal). But if you want a starting point, you can have a look at the JS implementation, a good starting point would be this area:
