Is thare a way of formating the footer so it's all on one line,
song name, copyright info .............................
No this is not currently possible. You can see that it's already listed on our Feature Requests page.
Martin - I am not on the development team, but I do know of a "workaround" that will get you there. It is a little ugly though.
First, Type everything (title, author and copyright) you want on one one line into the "copyright" field.
Then edit the song title field to include < > before and after the title (i.e. <Amazing Grace>), which hides the title.
Last, create a blank author and substitute that for the actual author.
Like I said - it's ugly. But if you really really need it... remember you will lose a lot: no more author lookup/sort in the Songs menu, CCLI reporting will have to be manual, annoying bracket in front of song names in the menus, etc.
Better Alternative - apply a smaller typeface to the footer in the Theme layout.
