@nlyxe thanks for your question, and welcome!
Pipeline Steps and Task Templates currently don’t have that sort of usage information baked into the UI, and I can see how that’d be useful to have at your disposal. I’d recommend submitting a feature request to our product team.
This sort of info could be queried for with the API. You’d essentially need to iterate through each, and then query for a count of the number of entities using it. I.e. for each Task Template, query the entity type for which it is for, then query for a count of all of those entities where the “Task Template” field is populated with that template.
