It's a good thing this "software" is free
This is the most horrible software I've ever tried to use. It is the opposite of user friendly. It's user vicious. It's the worst experience I've ever had. You need to do some major work on this program. It has numerous bugs, and it is about as intuitive as tax law. I would be embarrassed to release this pathetic piece of crap to the public.
When I load a style scheme I've saved before, none of the preset style specifications work. All the old defaults are in effect and the new styles I saved and want to use again are ignored.
When I enter lyrics, then erase them, then start over and enter them again, this idiotic program thinks I'm entering the second verse and won't let me enter the first verse again.
None of the margins and distance specs make any sense, and they don't do what they should, and what the user would naturally and logically expect them to.
When I change the font or margin or distance or any other attribute of the score, it should immediately visually reflect the change I made. This crap doesn't do that. So I have no idea if what I did had any effect. If I close the score and reload it, sometimes those changes have finally been applied. But until then, I can only guess whether what I did was what I should expect it would do, and whether it actually did it. This is asinine.
I have to fight with this nightmare tooth and nail to get it to do what I want. It makes me want to delete it and use something that was developed by someone with a brain who knows how to write software. How sad that a free open source music notation program has to be a useless piece of crap. It gives free open source software a bad name.
Please learn how to write software, learn how to write software that works and makes sense (as opposed to the incoherent mess this is), and learn what it means to create a user experience that is enjoyable and productive rather than a horrific frustrating waste of time.
