Frequently I encounter torrents containing hundreds of files and multiple file types, but I'm only interested in specific file types, and it's time-consuming to scroll through the list of files to uncheck the "download" column for the ones I don't want or can't use (yes, sometimes I deselect all files and then "opt-in" the files I want, to save time).
If there was a sortable "file type" column, this would be an easy process.
