You may (or perhaps, may not) remember the demo of Maxwell Mouse
we released last year. It's been very stop/start, but the full version is in progress, although there's a long way to go.
To help people's interest, and to give me an incentive to get a move on, I've started up a blog to track development, and you can find that here:
I'll try and update it as often as I can, maybe two or three times a month, depending on how things go and how much time I have. Hopefully people will enjoy it, and I'll post things on this thread too (and feel free to ask questions, offer ideas, and so on too!).
