Adding Class Abilities from a different class

[markenbach]

Any tips on how to add Class Features from a different class to my character?

My DM is having us add a "Gestalt" level every 3rd character level.

By his terms, this means that we pick a Gestalt Class and every 3rd level we may add the class features of that class. These features are in addition to the normal class features and do not add to character level and stuff like HP, skills and saves are not effected.

I'm playing a Slayer with a Fighter gestalt class. So far, I've just been adding the bonus feats and such in the Adjust field, but adding other Fighter specific class features is a little trickier.

I would like to find a way to integrate these abilities into my character a bit more cleanly, perhaps with the Editor feature, but that thing is a bit confusing to me.

Any help would be appreciated.
