brad12kx I don't see a way around editing your song database. You have three possible approaches. All of them involve changing your song entries so that every occurrence of an indented line is changed to one of the following:
{t}Verse line {/t}
where t is a formatting tag that is defined as <span style="margin-left:50px">
or however many pixels you want to indent
{t}{/t}Verse line
where t is a formatting tag that is defined as
or however many spaces you want to indent
You can do a mass edit using SQL with software such as DB Browser for SQLite. It will work on the database, which is songs/songs.sqlite in your OpenLP data folder.
A safer way would be to export your song database to an empty folder. This makes one file per song. Then find a way to do a global search and replace on each file. Windows, Linux and Mac all have ways to doing this from the command line, so you don't have to edit each file. The first suggest approach is the best, I think.
