Improve the Desktop Refresh UI

It would be excellent to improve the desktop refresh UI.

For large reports it's very hard to track progress and use the information to improve.

• Currently all tables start in "Creating connection in model" which of course they aren't.
• The status icon spinner is spinning for every table until they all finish, of course they're not all busy.
• It's a small non-resizable window, and you have to scroll around to see what's happening.
• Once the refresh finishes, the window closes with no record of what happened.

It would be great to improve the UI:

• Show what each source is really doing - "Waiting", "Retreiving schema information", "Loading data", "Processing loaded data and calculating columns", "Complete".
  Change the spinner to show the status - waiting (spinner)/working (something else!)/complete (tick).
• Show the start time and completion time for each table (and peak memory used would be a godsend).
• Make the window resizable, scroll to the last udpated status (if the user hasn't scrolled manually elsewhere).
• Don't close the window at the end, allow us to save it to a file (or table), perhaps with even more detailed logging information.

Finally - as many others have requested - I'd love something similar to the above log to be available somewhere for refreshes on the PowerBI service.
