Here’s what’s been and due to be released for PowerBI, currently from October 2019 to March 2021, in a PowerBI dashboard.
Oh yeah! Goodbye forever, crappy DAX editor… hello, real development and debugging tools. Is it September yet?
I’m waiting for the new External Tools menu which opens DAX Studio, Tabular Editor… from within PowerBI Desktop, coming soon!.
I think we have exactly the same wishlist. My understanding is the XMLA read/write is what will enable the external tools menu.
