Enabled vs. disabled vs. neither
Plugins occupy one of three states: State Meaning In plugins.enabled ? In plugins.disabled ? enabled Loaded on next session Yes No disabled Explicitly off - won't load even if also in enabled (irrelevant) Yes not enabled Discovered but never opted in No No The default for a newly-installed or bundled plugin is not enabled . hermes plugins list shows all three distinct states so you can tell what's been explicitly turned off vs. what's just waiting to be enabled. In a running session, /plugins shows which plugins are currently loaded.
