Yeah, that's a problem, admittedly. I'll be modifying the Mac version to add more effective auto-downloading. I'll try to anyway...Applescript makes me die a little inside.
Even if you could just put a version number and release date in the Admin section of our site that would be super helpful. I could then check it regularly and download it when I see a new release date and version. Right now, I have to just download it blindly at random times, and I really never know whether its a new version or not.
None the less, keep up the great work. We really like most of the features you've implemented.
