I like these ideas. As the Marketplace grows I would like to see it continue to evolve. I think version numbers are important information when purchasing. I would also consider compatibility information very valuable. I think the permanency of reviews is important. Its also a great example of the review option in to IPS4. Perhaps allowing 1 edit or something like that would be a fair compromise. As I have said before, I would love to hear more ideas for how Marketplace can be better for users and contributors.
