Slight confusion about Actions and Action Groups

I assume, that the few Action Groups from the Examples page http://getdrafts.com/actions/examples are more or less the same as some from the Action Directory https://actions.getdrafts.com/drafts_action_groups

I seem to have seen differences …

But what about the single Actions from https://actions.getdrafts.com/drafts_actions ?
Are all Actions from the above Action Groups also listed here?

I assume that the list of single Actions is larger than those from the given Action Groups.
But is this a real subset?

I´m a completionalist and do not want to miss something :wink:

Sorry for the confusing questions …

Not all actions contained in an action group have been shared to the directory. It depends on what the person did when publishing their actions to the directory.

Ah, OK.
So I need to hunt more deep into the forest :wink:

Thanks!
