Another issue I find is lack of education given to users after installing software/application. Commands like Ctrl/Cmd + F are not easy to discover. Especially for the people with lesser computer literacy. I believe a simple tour of how stuff in your application will work; right after installing it will give some idea to majority of users. Of course not everyone will sit through whole tour but there needs to be some sort of education of end-users in interactive format rather than typical "read me" files.
