GUI - Plugins tab
You can directly access all the Kray Master plugins from this panel.
Add/Edit ... button will open the interface of the plugin.
Remove will remove the plugin from the scene.
Enable button helps you temporarily disable plugin without removing it from the scene.
Note: when opening old scene that was saved with older version of Kray the "Enable" button may not show plugin is present correctly. The way to overcome this problem is to make sure Kray is on the top of the plugins list.
