It supports custom headers, basic authentication, saved favorite requests, and request history, with import and export for favorites. The description says storage is used for favorite and historic requests and that incognito requests are not stored.

Shared hosts - 7 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
