Improve the Column selector
Please improve the usability of this dialog.
* Add support for range-selecting columns indices by entering 2-9 to select columns 2 thru 9.
* When the newly added line is out of sights, scroll down automatically to show it
* When press Enter in the value-editbox, add a new line and move the cursor to its editbox
Now you would need to switch from keyboard to mouse to click +, then scroll down, click in the editbox and start typing
We will take a look at this. Thanks!
* when a column has been used (eg already added to a particular include/exclude list) remove it from the auto-complete
* improve usability of the selector to facilitate keyboard only (minimal mouse) selection of fields
