Vertical "design view" of all columns with ability to change type

I would appreciate a vertical design view for editing all the columns in my board, so I can see all my columns in a single vertical line, and the type of column assigned to each data column. It would look similar to the “item default values” box, but instead of the value, it would show my what type of column is currently set there.

The purpose of this view would be to sort and change columns types, not to display the data. The problem this solves is the right-left scrolling to see if I remembered to include that one column, and also verify what type of data each column is designed to store. Would be great to download the list into Excel too.
