Disklavier

Hi. I just downloaded the last version of disklavier controller for iphone where in details section is a page named "song title" to seach songs. Unfortunately I cannot find this page on my iphone. Somebody can tell me where it is ? I have the impresion the firs version of disklavier controller is not accepting the new version as I do not see any change on the display and any time I go to Apple store he asked me to download again the same applicationathough I did already several times before ..... Strange, if somebody can help, this seach option is ver useful for me. Thank you. Julien
