Include the ability to filter by Status and Project within the search.
The search box above the Iterations tabs, should allow you to filter based on your search. The current search will bring back several results across multiple iterations. The amount of data returned is hard to read.
You should have a general search with filters (mentioned in other comments in this thread) and a simple way to search the current initiative.
Customize Time Frame - you should be able to customize the time frame (similar to Chart report for Item Distribution)
It would be helpful when doing Retrospectives and generally reviewing processes. For example I would like to download all Bugs for the past 3 iterations. Then using this data try to establish new test cases based on the bugs.
CSV Export - You should be able to download a CSV based on your search results. This will allow further data processing offline.
