I first want to say thank you for all the development work on this tool!
It would be extra work on your end, but it would be cool have some pre-report options. It would be nice to have different parts of the report togglable, most except the performance area. Personally I love the reporting of rewards at the end, but could see some that would not want to disclose that information.
It would be interesting to have an option on the summoners used and monsters used to shrink or expand the list. Maybe a drop down 5,10,15,25,50,100 for the monsters. A drop toggle for the summoners 10 or all (sometimes I just want to see how well I did with a summoner just outside of the top 10).
