I've always wondered why did you choose this kind of configuration approach to your naming style, I mean, couldn't you let the user write code and let R# copycat or deduce the conventions based on the actual code the user provided? it's much easier to express how you want the code to look like rather than going through detailed configuration about it.
This feature can replace both the Formatting Style configuration and the Type Members Layout of R#.
This is obviously a suggestion but I think that it's much more intuitive than the current configuration that grows and grows with each new version of R#, this will ease some of the pain that we have to go through when we're configurating R#.
R# naming style is really primitive, how about changing it?
