Those are all good suggestions.
1. Several users have asked for the ability to auto-start the cam. It should be pretty easy to do, so I expect it will be in there pretty soon.
2. Several users have reported successfully using multiple cams on the same computer (on Mac and Windows) by copying the executable and running multiple instances. I understand the point you're making about crowding.
3. Other users have asked for this one as well, so there's a good chance it'll be in an upcoming version.
Currently, we're pretty focused on the Windows Beta test. Once that has calmed down a little, we can focus on adding these features and others that have been requested.
If you have any other suggestions, let us know.
