Stop returning cursor to first column in Dataflow creation and add "Find column"

When selecting a column in Power Query Online and expanding the column drop down to see values within that column, on close it returns the cursor to the first column.

This is fairly frustrating and slows development as when you are exploring a table that is a large number of columns, you get forced to return to the first column and then have to scroll to find where you were.

The expected behaviour should be to leave the cursor in the current column.

It would also be advantageous to be able to search for a column by name.
