Very nice start, of course. If it's completely new, I'm amazed that a small group of users can get a somewhat obscurely helpful (yet still very helpful, almost neccessary) tool into the program with just a simple request. Very cool. Unfortuneatly, it doesn't really help (as it is now), as my MP3s are stored in MC with filenames starting with "\\josh\joshmusic\...". It gives me an error when I try to upload a file while "Auto-Create Directories..." is enabled (quite understandably, no drive letter) and I can upload normally when it isn't.
Although you're probably hard at work on this problem/feature request (well, not right now, it's kinda late), to reiterate, it would be nice if you could, either in a handheld plugin or a general file-management tool, do the exact thing you do with "Rename Files From Properties". You would have control over both the destination root directory, the subdirectory structure underneath it, and the destination filename. All of these based on ID3 tags. That's my ideal prototype.
The reason why I really need this (or some similar) amount of power is that my MP3 collection is segregated into two seperate filenaming schemes in different folders. Even if it wasn't, I would still probably want to have the ability to use a different naming scheme for a tiny small-screened MP3 player than for a large computer with a mouse, keyboard, and 1152x864 resolution screen. They have different needs.
I would be glad to test any further prototypes or provide further feedback.
Many, many thanks!
