Diff Enhance request

Hi,

I like the visual diff tool which is part of IDEA. Currently it has no feature of ignoring whitespaces.

My request is to add two new options:
1. Ignore empty lines, so

will show no differences with

2. Ignore order of method, so

will show no differences with

There should be possibility of choosing any combination of ignoring whitespaces, new lines and method order.

Best regards
