yeah, it would be one of the best improvements to this game ever. i've been having that idea for a long time. but on the other hand i fear it would ruin an effort part of the gameplay loop a bit and might suck the fun out of it. the core loop is "search-and-complete" the holes that the player left, and by automating the "search" part, we might no longer find satisfaction in "complete", because there will be no effort, no point in the reward. i've been thinking about it too much :)
but it is true that it is also not a trivial task, as we would need to design a small piece of UI.
still, maybe some day.
