Would like the ability for a Plan License User to have access to the API. Their API access would mirror their in-tool access. This would only give them access to data and actions that they can access in the UI. They would only be able to query projects/tasks/issues/etc. that they have access to see. This would allow them to use the API to access their data for reporting, building custom spread sheets, populating power-point presentations, or whatever they need.
