Reports>Encounters Details Checked By Default.
when viewing all the encounters of a particular day, it is more meaningful display to have the Details check box checked.
Just in case u want to have it auto checked by default
goto interfave>reports>encounters_report.php
goto line 68, change the default false in the end of the line to true like in the encircled red.
Then each time the check box next to details will be auto checked.
