Very good, one annoyance

Would have given excellent except for one annoying procedural difficulty. If you need to rearrange the order of the files, for the most part, you can’t just drag a file from where it is to the location order you want it. You have to step it throught the ladder of files one file at a time. If you try to drag it past multiple files it just stays where it is.
