In the MISTRO Pocket program under options there are a couple of other things you can configure.  The Current User is the default technician on all treatment and mating events.  If your herd is split into herd groups you can select the Use herd groups tick box for it to only select cows from a specific group.  You can select if you want the time when adding preg test results to be in weeks or days.  You can also turn off the splash screen to speed up the starting of MISTRO Pocket.
