Furthermore it would be better if the applications available for download, were confined to the software center or at least confined to a separate perspective, so you can focus on the applications you have already installed -- after all, one must expect that the user has installed the various applications with the intention of using them, hence the Dash UI should be optimized for _use_ rather than installation, there are / can be other ways that are more appropriate for discovering new not-yet-installed applications.
