Thanks so much, really glad you like it! Keeping it free and making it fit naturally into OBS has been the goal from the start.
Great question, and it's partly yes. Font size, position, margins and backgrounds are all set per output, so the projector and the stream can look completely different. Line grouping (which lines go together on a slide) is set per song, so every output gets the same lines at the same moment. There's no per-output rule like "4 lines here, 2 lines there".
The closest thing is Max Lines, which you set separately on each output, along with a minimum font size. Say you set the stream output to 2 max lines with a 36px minimum. When a lyric would wrap onto a third line, LyricDisplay shrinks the text until it fits in 2 lines, never going below 36px. The projector can have max lines off, or set higher, and keep its big font. You can also lock the lower-third background band to the max lines setting, so the band is always the right height.
One catch: max lines controls wrapping, not slide breaks. If a slide itself has 4 lines, a 2-line output can't split it into two halves. It shrinks the text, and if it still won't fit, it cuts off after line 2. So for a projector-plus-lower-third setup, it works best to build songs in 2-line slides. The projector just shows them bigger, and the stream fits them neatly into the lower third.
Hope that helps, and feel free to share any feedback once you've tried it!
