Please add a way to organize documents notes, sermons etc... If you create more than one sermon in a series they are all jumbled together with the rest of your sermons. Simple solution would to be able to group by more columns. Maybe add the ability to add and group by tags, sermon series ?
A more robust solution would be to have a documents screen that is divided into three sections. Tags or filters on the left. Document list in the middle and a preview window on the right. This would allow you to click a tag on the left that would filter out Documents in the middle and then you could click on each document to preview it to see if it is the one you want to open.
