As a beginning of this suggestion, I'd like to quote Julien Lebosquain from thread http://devnet.jetbrains.net/message/5317899#5317899:
Sorry for hijacking the thread, but the ability to disable various features is really missing from R#.
I mean, add options for almost everything. We can disable and configure each one of the C# inspections, but there is no options to completely disable support for a given language, or formatting for a given type of file. Every new feature you're adding should have its corresponding option.
I fully agree with the author of these lines. It is more than annoying that I cannot control what R# does to my code, and what it does not.

This way atleast I could quickly find out what formatting was applied. You could do more and add links from this log to corresponding settings, so if I click on the name of the style/feature/option xxx I could get into that settings and modify 'em if needed.
Like with the suggestions, when it highlights my code and from the button appearing to the left I can change options for this notification. All this is really a must for usability-targeted software.
Since I'm still thinking R# is a great tool, I believe I'm moving back to version 5 until this gets added.
