This editor is almost perfect, but there's one reason that keeps me from using it...and it's a matter that I Think would be reasonably fixed or modified as an option. Right now, by default, a folder is organized in alphabetically, but backwards. So for example. If I have documents called 03_01, 03_02 and 03_03, the file viewer displays the order as 03_03, 03_02, 03_01. I know that I can drag these around and reorder, but I think it would make more sense to reverse the order.
At the very least it would be great to have the option of sorting the filelist. I create all of my documents with this nomenclature, so it's really difficult for me to get used to the default order.
Other than that, this editor is perfect. Keep up the great work.
