GW2 Stuff overlay
That overlay doesn’t interact with the game at all, at least the one I tried. I ended up not liking it because of it’s size and ‘how’ it sat on the window. It basically is designed to stay on top of the GW2 game (windowed mode), but it’s not like it’s an add-on. It doesn’t have focus. So when they tell you you can ‘right click’ on it to bring up this, that or the other, you really have to alt-tab to it (unless they changed how it works), and then you can interact with it.
But unlike the super-teleport-cheater-6000 thing that those people were using to pop around from node to node, and you’d see them dead in a rock from time to time, it isn’t interacting with the game client at all, other than to say “stay on top of this window”. It gets it’s information from the provided APIs, same as the web site, so I gather.
Now, if they deem that using it gives you an unfair advantage to accidentally die quicker than your opponent if you are accidentally alt-tabbed to it, though it wouldn’t look too different than not being, and you start mashing key strokes and nothing happens (much like seeing “wwwwwwwwwaaadddsss1111www11122 sorry” in chat from time to time), then I suppose it might give an unfair advantage to ‘not’ you who is attacking you. 
Now, that was my experience with the very first edition of it. In fairness, it could have changed since then. I’d just as soon alt-tab and use the script for the audio notification, that suits me fine. What I’d really like is a mobile app.
