Up until now we have had the "simple titles" provided as a package by LilyPond, but it is possible to create more tailored titles using the LilyPond markup language and as we have an interface to that (in the Multi-line Text and Symbol thingy) I realized we could let people create their own customized titles. So there is a new command under Score->Titles called Custom Titles, which lets you create as many lines of titles as you wish. Each line offers to let you put text on the left, right and centered, which you can adjust as to font etc as usual. This command is an extension of the Filled Title Line command which is now retired.
