If PS touch had a way to easily create repeating background textures similar to how one would do it with PS for desktops (filter>offset>wrap, then blend or clone stamp tool the edges) I think this app would be worth it's weight in gold.
You should create an idea thread for this feature request and describe why you think this functionality would be useful for yourself and others. Do you do a lot of creation of seemless backgrounds for webpages? Adobe uses the ideas threads for feature requests, having one idea per thread and have others vote on the idea if they like it.
