Query Editor has no UNDO :(

[willems1]

I want to undo changes to a query. Undo should be available everywhere!!

Just another example of appalling design decisions by Microsoft. That they can continue to ship products that can instantly delete your work (you clicked an error value in a column? hope you didn't need all those subsequent steps!), and rip off customers for the pleasure, just shows how bad the product team are at their jobs. Maybe don't make an IDE where you cannot save anything until all code is running perfectly?

This needs to be made available in both Gen1 and Gen2 dataflows
