Theme specific questions should usually go to the author of the theme author but if I understand your questions correctly you want the ability to show all posts on the front page. WordPress (no cms to my knowledge) doesn’t work this way. However if you navigate to the “reading” section of your admin panel you can set the amount of posts that will populate the front page before pagination begins. Just set it to a number higher then the amount of posts you have on your site and you should be good.
