A template determines what ATL does and does not show in the main overview.
There are 44 different columns that can be enabled or disabled.
You can click on [?] behind every element to read a short description.
Per element there are 3 options;
1) on / off. For some stats there is a difference between on # and on %;
this means that either a number (#) or a percentage (%) is shown.
2) the second field - the first text field, sets the title. This title is displayed at the top of the column in the main overview
3) the third field - the second text field, set the background color of that column.
