When I need to find any action type that is making use of a particular function, I have to open each action type that triggers a function one at a time. Short of exporting the ontology as JSON, I can’t find which action types use the given function at a glance.
If there is no ability for that within the Ontology Manager, I would like to suggest adding it to the page for foundry functions, with indicators of which action type uses them and at what version.
