Search Hymn Field - Update tip text to include song #

The new version of the app allows to search by hymn number. It might be helpful to update the search field "tip text" from "search by title or lyrics" to "search by title, lyrics or hymn number."   Had I not read the version description notes I probably would not have discovered the feature. Even after reading about it,  I initially couldn't find where to search for a hymn number. I kept looking past that search field because it specifically said "search by title or lyrics" and didn't indicate that I could also put a hymn number in that field also.
