Both the service and strength section of the report now contain a single tab instead of two. On this tab the user can now select as many combinations as they want to be summarized.
Updated navigation of data grids in the program.
Multiple bug fixes.
v3.5.0 -
New Features
Added option under File → Options to reverse the table order in the program. When reversed, all output tables will have the top of the column be the top of the table
