How many other people are working on emplode?

In general, nobody else works on emplode. Peter and Richard have been known to hack on it. Before that, Andrew and Haydn were my co-conspirators, but the last round of redundancies did for them.

Gremlins sneaking in at night modifying your source? :)

I've been out of the office for most of the last month, so it's entirely possible that people have been sneaking features in there. I'll check when we're all back at work properly on Wednesday.

I'd really like to be able to (add total track# to) all my tracks (without re-uploading them :)

That'll probably be as simple as another edit box on the properties dialog. I'll look into it.
