Right now there is a table with various items, the last item is a checkbox called "include in the report"
This table is usually so wide that users need to scroll to be able to check this or they don't even see that the individual items need to be checked to be included. This is a bad UI design, but it has easy fix, just move the checkbox to be the first item.
The code responsible for the table is here: https://github.com/huggle/huggle3-qt-lx/blob/master/src/huggle_ui/reportuser.cpp
