Ability to select column ranges would be useful. When dealing with wide files being able to select sequential range of columns without specifying each column will improve the usability. 

So instead of this:
select columns[1], columns[2], columns[3], columns[8], columns[9], columns[10] from `data.csv`

use this:
select columns[1-3], columns[8-10] from `data.csv`

On a sidenote for extremely wide files (10K columns) the only way to query the data or load it into native tables is to chop it up first as Java is runnint out of the constant limits (error: too many constants) when querying the file directly or creating a table from it. This issue has been reported elsewhere.
