I received a fair amount of feedback about the first version of the Power Tools mainly focused around the UI (people like modern today) and around "bug #1", which prevented files from uploading to the correct path in IsolatedStorage.
I've just pushed a major UI rehaul to something somewhat more Metro-ish, loosely styled off Zune. It uses a combination of custom styles that you can find in the source tree and MahApps.Metro. I've also fixed the upload bug and other miscellaneous bits of polish here and there. This probably should have been a 2.0 or a 1.5 but it seemed to soon 🙂
As always, feedback is welcome, though a reminder that this is not a Microsoft official tool.
