My point is, as the author himself admits, it is in development and far from perfect. For me it produced a whole load of false positives and only managed to find 2 collectibles that were fully exposed in open spaces. I would have found those myself easily had I not been testing the system. I tried it several times with the same results. Perhaps with some more development it will become a must-have tool in the same way as the combat sims, but right now it's a novelty - fun to try but little practical value.
When you have a lv50 island with hardly any open space left, the very high chance of collectibles being partially or fully obscured by buildings makes this tool less and less useful in it's current form. Far better to learn the areas where they are likely to spawn: I find them again and again in the same places
But then, what's the fun in making everything easy? why do people want everything in the game handed to them on a plate? I get a little buzz if I find a batch of 15 on my own.
