What do you mean by "Address search/input" option? If you mean having to ability to "Go to" a particular address, that (among other things) is coming in the next version. In the meantime, there's a workaround: Download a route from the address you'd like to see to that same address (yes, both text fields - use copy/paste), then use "Go to -> Next Waypoint". That's basically what the "Go to -> Address..." feature is going to do. Yes, that means you'll need internet access to go to an address - you have to remember that Maemo Mapper is free and thus doesn't have ANY of that expensive Navteq street data, so it can't do routing or address-finding on its own. It works only with bitmap images.
