Feel free to add other feature requests in the comments section. I know that this is premature in the sense that Logos has several major enhancements in the works - PBB, sermons ... and then hopefully Notes and Handouts. But I also think that this is a request that will take some time for people to see the possibilities - and how those possibilities fit into their prayer life. It is not geared just to fixed prayer - it's intent is to support praying with scripture, praise and thanksgiving ... essentially the wide breadth of prayer as Richard Foster describes it.
