Currently, eggs are exported in json format. Eggs can contain a lot of multiline strings, which makes it very hard to read them in json format.

YAML has much better support for multiline strings (see here) which would make it much easier to modify eggs as code and see changes in Pull Requests.
In addition YAML is easier to read and we've converted wings to use ya

I would need to get each user's hourly rate using the API (this should be one of the user preferences): how should I do it?

I'm not sure if it's already feasible (and I just cannot find it) or if this is missing.

Thanks in advance for your help.

Ciao,
Alberto
