An improvement to the sermon editor which I think could be simple to implement would be the ability to change the translation of all passages at once, like we can in harmonies. I sometimes preach places where a different translation is exprected, and a simple drop down would save some trouble. If my current translation is the HCSB, for example, and all of my passages except one are the HCSB, I would expect selecting ESV from that drop down box would change all of the other passages to ESV, and leave the one where I had manually selected a translation the same.
