[SUPPORT] Advanced Turn Based Tile Toolkit

Hi
I think you missed my previous post.
I just bought the toolkit and it is great.
How easy would it be to add scrolling to your kit (ie mouse to edge of screen moves map) as my game will have large maps.
I went through your tuts - in #6 I think it was, you show updated tiles vs decals vs landscape/terrain.
In your experience, for large maps which would be the best way to go? (memory/performance-wise).
Thanks in advance
