Even better but would like more updates

I really like this app, but since it looks like the developer takes suggestions on updates, here is a few things I would like to see in the future. Would really like to be able to break down dives by boat vs shore, see number of night dives, number of nitrox dives, etc. Would prefer it if, when adding new dives, start and stop time defaulted to 00:00. Would also like to have the option of deleting graphs like the dive by hour.
