I needed a plugin that will do a few things. 1. Not load data from a Search expression but still returns the aggregate of the list (which is what :count does)
2. Trigger events when:
   a. the data source gets a new record (Event: List is updated)
   b. a record gets removed from the data source (Event: List is reduced)
   c. the data source is completely loaded into the plugin ie. the plugin's "List" state and the data source list counts, match (Event: List loaded completely )
   d. the loading starts
   e. a loading process completes
