poorly designed GUI, very very sad

There are only two options to find words, i,e. search(word input) and word-list(alphabetical list). There is no search history window, no infomation(about) window, no bookmarks, no index, no landscape mode (only portrait), no sophisticated internal cross reference(link). Worst of all, partial word matching(search) cannot be done. I tried to enter "bri" looking for "brittle", but as soon as I entered the three letters, input-window shows "rbi" not "bri", then a few seconds later "ALERT no matches found"!!! It also claims that the iPad version is optimized for the larger visual experience of that device, but I dont see any optimaization other than the rather vacant space which is left unused. Very professional and auhentic information is confined in a primitive implementation. I should have bought a printed book.
