Hello, firstly, please update to the recent version of the plugin, it has a feature called Zoom Method, you can use that instead of using extra tile. Zoom Method: 2.0 <- Write it like this.
I'm using 1.0.1 version. All it does just provides zoom (2.0 = x2, 3.0 = x3 etc.), but my character is still isn't centered when the character is around the edge of a map. I'm looking to keep them centered I was under impression it's possible with this plugin.
