Is there a good resource for reading up on time travel (or the log of actions) in Om Next? I'm mostly interested in how do I tell Om Next not to store (and replay) async things, and only store the things that actually mutate my state.

I mean, if I have a fetch-data-from-server event, action, effect, whatever you want to call it, I won't want to replay the server request, but I do want to replay the moment when the payload is inserted into the application state. Maybe I'd still like to store the request in a log, so that I can easily see what my user did, but I can't replay the request, obviously.

How does Om Next handle that? Or is that my own concern?
