Provide error information within the Gen2 dataflow...

When a Gen2 dataflow fails in Fabric, the Power Query editor provides no in-context error details. You must exit the editor and open the “Recent Runs” pane to see diagnostics—interrupting your workflow. Please surface run errors (messages and logs) directly within the Power Query interface so users can troubleshoot without leaving the editor.

Diagnostic information in the "Recent Runs" window is like hanging a toilet paper roll holder in the garage instead of the bathroom. Maybe kind of nice, but it's not where I do my business.
