Congratulations, Lilypond relationship, getting ideas for gui

Hallo,

Thank you for this great piece of software. It's steadily getting better.

What I like especially is the fantastic visual output.
I think it is the only software that does e.g. shorten ledger lines if having accidentals as Lilypond does.
Comparing Lilypond output with Musescore's I find very little differences. So although I really like the fact that you can export to Lilypond I'm very happy saying there's no need to regarding the visual appearance.
So how it comes that they are so similar?

Thanks

PS: It's a pitty though that for work I would also have to have Tabs and Guitar Diagrams. Hopefully...
PPS: It would be worth looking into another Notation software called Primus. (//www.columbussoft.de )
They have good ideas regarding the gui (even better than Sibelius) so e.g. you can choose different barlines only by right clicking on the existing one. Same with key or time signatures.
