Smarter Auto Mode

[Hetfield]

This is not as easy to implement as you describe i'm afraid. If you would want this to work you would actually need 2 transfers for each file. The first "transfer" would only get the first few bytes to check the header basically, then FlashFXP would need to initiate the second transfer to get the file in the appropiate mode. This kind of overhead would be out of the question if you ask me.
