I'm glad that P5 is seeing how important the original filenames are to us producers, but in addition to being able to search for a file using it's original name, I would like to see the original filename added to the "Edit Item" page, perhaps under the preview.
Searching for a file by it's original name is a step in the right direction, but what if I don't know the file's original name? I can't search for it. But if I visually see it, then hit "edit clip," I would be able to see my original name for the clip right there on the page.
As of now, I'll stop adding my unique ID number to the titles, but I will continue to add it to the description. That right there is a big help when I have to find a clip on my hard drive in my growing collection.
