As per subject, an option to erase statistics per wad/tag/entire database, and an option not to record any statistics at all would be nice.

Two of these features already exist. There is a checkbox for save statistics in the launch dialog. You can delete all statistics for wad by selecting all the rows in the statistics tab, right click and select delete.
