It would be good to have a tag editor for creating and editing tags when needed:
Multiple tags can be associated with a single trigger. This can be useful depending on the trigger event(s). Each tag can also have a different persistence mode.
Tags can have a name unique from the trigger. The default tag naming scheme is good, however, it could be useful to override this especially when you have multiple tags per trigger.
Allow specifying the color of a tag. This would be useful in dialogs where you select a tag to attach to a techno object. By default it could use the color associated with the tag's trigger, with an optional override.
