tapatalk does just that mate, i have a widget on my homescreen which takes me straight to the forum just the same as the app would, you can browse with ease, pm, it even jumps to the latest post you've read if you so wish, really great app!
i think if you goto the tapatalk app it will bring digi up, just press back all the way to the start and i think that should bring up the search again!
tap on the app and then it opens on your favs press back button the menu is now browse:search: favourites:most active: follow us on twitter:
just choose your option
