I want to suggest to you new usefull feature. Please add ability to ReSharper to find all files which are not included in project(s). For some reasons unprojected files appear (i.e. incorrect merging, etc) and we all know how to see such files (by clicking "Show hidden files" in Solution Explorer). But very diffcult to clean solution with many folders from hidden files. It will be good to have the feature which is show all unprojected files in solution and allow to delete selected of them.
