Well Youngs, I see what you mean, but for those of us with slow or laggy computers, having to go back and forth especially when we are training lots of pets can be time consuming. Most of the time I have no life or nothing to do so this is fine, but for those who love it here, and are busy most of the day, they may not have time to sit and wait.
Now this may not apply to many, but on some days I know it does to me.
