In version 2.0 of the ReSharper we're going to extend the refactoring pipeline to add better conflict support and optional changes (for possible occurences in comments and string literals). Note that it mainly won't affect your usual refactoring experience as long as you don't get any conflicts.
But we sometimes also think about creating some shorthands for running refactorings with default options (like Google's I'm Feeling Lucky button) - for example, a method can be extracted with default options for return value, etc. with just a single shortcut. It will extract method and create live template over it to let user specify name of the method and its parameters. Somewhat similar approach we utilize in renaming locals and searching references. In the latter case we have one shortcut (Alt+F7) for running search with last specified options and another (Shift+Alf+F7) for specifying all options and then running the search.
Of couse you won't be lucky all the time so the question is: which refactorings you feel match this scheme well and which options you think should be configurable even in such "quick" scenario?
