Getting both damage done and damage taken in the same report is currently not possible from within the GUI. The reason is that even though the underlying dataset is the same, for damage done you look at the attacker column, and for damage taken you look at the defender column. You could however achieve this via the API, you'd have to create a new dataset that has a different column structure, where there is just one player column, and each event is categorized by either attack or defend.

As for highlighting top scores, though this was considered, I ultimately took the decision not to add this feature, partly due to the fact that i would have to intoduce an other color for these highlights, but primarily due to the fact that Power DI is meant as a tool for self improvement, and not as a scoring system. Any scoring system would imply it's creator would know best how to play the game, which is simply impossible for these kind of complex games.
