This software does not include any hacks or cheats, and makes use of official APIs built into the game and built by ArenaNet. Using this software is in no way different than using other GW2 informational websites, event trackers, and overlays.

No. Due to some technical reasons for how Fullscreen games take over the monitor, the overlay does not work when the game is running in fullscreen (at this time). The game must be running in Windowed or Windowed Fullscreen for it to properly overlay on top of the game. It's possible that this may be added in the future.
No. Mac OS is not supported at this time.
Maybe! For all feature requests and suggestions, head over to the Forums.
