I am Catalin from www.xdesksoftware.com , our program XFilesDialog is one of the "winners" of the review and if you are a member of this site you can now get it with a decent discount !!! (see the special members-only forums for more details on that).
We can also let you know that we were already keeping an eye on some of the interesting ideas also suggested on this forum (even if for instance some of them can already be achieved with some extra work on configuration - our program is very powerful).
Please let us know what you think about XFilesDialog ... suggestions are always welcome!
