I posted this idea in ideas.powerbi.com as well, but it is quite unclear to me whether the powerbi databricks connector is in fact made by MS or Databricks, so I post it here as well!

It is possible to add comments/descriptions to databricks database columns, and in PowerBi a column can have a column description which can pop up when hovering over the column name. When importing a table from databricks using the powerbi databricks connector, it would be nice if it imported the column got the description from the corresponding column in databricks!
