What Should Be Added or Changed?

Saws should take longer to cut down large trees. The time should be configurable since not everyone will like this.

Why Should This Be Done?

Cutting down a tree with 117 log blocks can be done in less than 3 seconds with a basic iron saw. The saw should eliminate the annoyance of building dirt ladders and tearing them down, but shouldn't make the actual wood chopping significantly faster. As it currently stands, the saw practically eliminates any need to automate wood gathering.
