The cart loading process allows you to pick a file that is not in the library.
The same dialogue/process should be available for the empty white box in "manual" mode.

Hi Mark,
It is possible to play any file without loading it into the library by just dragging and dropping it from Windows Explorer

I didn't realise that. It would still be better to have the "click through" file selection process that the carts have as I guess many people run PlayIt live in full screen mode.

For completeness, it would be good if any file picked from a network drive were cached locally as well.
