What is a valid plug-in status for a plug-in that has been added to a vSphere client?

After a plug-in is added to the vSphere Client, it can be set to either Enabled or Disabled state via the plug-in manager. 'Disabled' is a valid and recognized status indicating the plug-in is registered but not currently active. Administrators can toggle this state without removing the plug-in.

'Unknown' is not a standard, valid status displayed in the vSphere Client plug-in manager for a successfully added plug-in.

'Stopped' is not a recognized plug-in status in the vSphere Client; plug-ins use Enabled/Disabled terminology, not running-state terminology.

'Installed' is not a labeled status field in the vSphere Client plug-in manager interface; the state reflects activation, not installation.
