Needs more control over text file diff operations

So far my biggest gripe is that it has no way to set the diff to ignore white space changes, in paricular this is very annoying when dealing with code format changes.
To match the power of other tools it really needs a way to set diff options based on file type, so ignoring indentation changes in java/c but show them in python.

Additionally It really needs to support direct edit of text files during merge instead of just block copy. When merging code conflicts it is frequently the case that you need to hand edit, taking elements of both changes.

It is other wise a very nice looking diff tool, that will hopfully get improvements to make it more useful in a development environment.
