I don't worry too much about the 'look' of the lyrics as they appear in the notation screen, but I am concerned how they appear in print format.

You can control the number of bars per line in the print version as well, but the size of the bar is always dependent on the bars per line. Fixed bar length. BIAB will try to print the lyrics under the note, but, especially with a series of eighth notes, it can be a problem. It is also an issue at the end of a line, where you may only have lyrics on the last couple of notes in the bar, and BIAB prints one of them as overflow. It seems BIAB is happy to let lyrics flow past their note, but will never start them early to fit them on a line or allow the last one to go beyond end of the staff.

But note based lyrics do stay with their note, so playing with bars per line will usually work
