"Power Query Studio" an Offline IDE/Editor for Power Query (M)

I would like to see an offline application that would have a UI which mirrors the DataFlow Editor, however, these would be the differences and enhancements:

• Replace the formula bar at the top with the query panel, to view the whole PQ script in one shot
• Only execute on demand (not when clicking on a transformation in the PQ list)
• Export/Import
• Export from PQ Studio as a JSON file
• Import into Data a Dataflow
• Import into a Power BI report
• Import into Excel (if excel compatible connectors are used)
• Intellisense like PQ editor in PBI/Excel (better than in the dataflow editor)
