I really only have one request, and though the title says developer docs, I'm not wanting something necessarily full blown. What I would like to request is that for plugins/themes listed on the site perhaps a third tab to go with the Detail and Usage tabs. This tab would be Developer.
On this tab, I would love to see any actions/filters that are available with a brief description so that I don't have to continue downloading, searching code for possibilities and what they are. In addition, perhaps any plugin calls I can make through my own custom plugins.
For example, to do something when the Membership 2 Pro plugin activates, you have:
do_action( 'ms_plugin_activation ', $this );
I know I can plug into this.
I know that I can make calls like:
add_action( 'ms_init', array($this, 'init_membership') );
and then pull the API from that to then do something like:
$member = $this->api->get_member($user->ID);
For the Members plugin, this would be easier because you have a docs folder (with methods, but not much in the form of hooks available) in the plugin with some information. But you have nothing included in the ProSites plugin of any such nature.
Could you please consider adding some of this to your documentation?
