Just because we haven't agreed with all your suggestions, doesn't mean that we think the search and view new content system is not important. These systems are not perfect and we will continue to improve them, but there won't be any dramatic changes in the near future. However, it is likely that we will add a setting to choose between using last post or unread posts in the near future. If there were larger changes to be made, that would happen in 3.1, but I wouldn't expect to see a dramatic change to the presentation of these features. I can't tell you for sure what will happen in 3.1 with these features, because we are still discussing this internally and evaluating feedback.
