WORKFLOW > TEAMLEADER PLUGIN
Plugins can be developed with TeamLeader’s plugin development kit, as a way to extend the functionality of TeamLeader. Once developed, a plugin can be added to the collaboration toolbox or as a task attachment. The plugin must first be registered with TeamLeader.
From within the Virtual Workshop, go WORKFLOW > TEAMLEADER PLUGIN. Add the plugin, indicating whether it should appear on the collaboration toolbox. For toolbox items, you may also specify an associated icon, which will appear on the toolbox.
