When replacing an app in the gallery, it appears that you always see the original upload date (which is good to have), and then simply a version number. It would be great if you could add an additoinal field that shows the most recent replace date. That way you would know that "SampleApp v4" is the 4th replacment, and that 4th replacement happened on date mm/dd/yyyy. Also, while it's replacing, there is no indication that it is doing the replace. An hour glass or some indicator telling you to sit tight would be nice.
