Annoying issue

I do like this app a lot, but I get extremely frustrated when I save a collage and try to add another image to it. It cannot be found as the app does not refresh the camera roll. I have to quit and restart the app in order to see the just saved collage. It would be ideal and great to have an option to refresh and get to see newly added photos/images. I kept pulling it down expecting to refresh as other apps behave to no avail.
