Hi, firstly thank you so much for the terrific software!
I realized that a feature that would be helpful would be the ability to select multiple columns from the auto complete windows.
For example if you want to select the first 29 out of 30 columns, but omit the last, hopefully right here you could hold down shift and down arrow through the columns that you want, stopping before the last one. Similarly you could use the ctrl+mouse to multi select columns.
