It's the kind of utility we want to add features to, so if you have any requests of general feedback, please don't hesitate to let us know and we'll add it to our own, already extensive list of new features we want to include in the next update. You can either email us at info@score-studios.jp or let us know on the forums.
Paul is writing a blog post about the why and how of DMTools, which will give you some more insight into the creation of this app and why he figured it'd turn out this useful!
In the meantime, you can get DMTools right now, here from the games page or here directly from the Appstore!
