G'day. So, today I learned that an int setting in Factorio will just silently ignore a change if it is actually a float; I kept popping in 4.5 for the chest radius because usually the extra half a tile makes it match "what I expect" for a 4 tile search radius. Of course, it didn't work -- chests stayed at zero.
Turns out that I never got told the value was wrong by the game, and it never told your mod anything, it just silently ignored my float and left the setting at the default value.
Since I'm probably not the only person who will ever do that, can I suggest using a float setting, not an int, even if you decide to round it internally to an int? At least then it'll (a) let you tell me only ints are available, or (b) just use what I think is the smart value, regardless of I'm correct. :)
PS: thanks for making this configurable. I strongly prefer fairly mild power increments, and infinite range definitely doesn't meet my idea of those, so I'm super-glad I can tone it down to what I think is reasonable.
