Feature details

It'd be handy to easily see if the transcoding process led to larger/smaller file sizes when looking at the completed queue. This to aid making the "Clear Succeeded" choice and deleting the source files. There's relatively infrequent situations where a transcoding of a file actually making the size worse. (This assumes 'quality' isn't necessarily the main goal)

An option to "customize columns" with a source file size would help for this.

Those are good ideas.
