Since the forum restricts each posting to a maximum of two notation clips, this message is in 2 parts.
PART 1:
In the version 1 forum, Vlaera asked:
"Is it possible to slur and Beam eighth notes that carry from left hand to right hand?"
In version 2 it can be done with a hidden staff, invisible noteheads, zero length stems and some hidden notes. I don't think it can be done in version 1. If you're a pianist, this would be a very good reason to upgrade to the Version 2 public preview.
Sample:
Open a new piano template file. Add an extra staff using Ctrl-A, and move it up (Ctrl-PgUp) so it's between the left and right hand staffs.
On the top staff, enter this:
!NoteWorthyComposerClip(2.0,Single)
|Clef|Type:Treble
|Note|Dur:8th,Slur|Pos:-13z|Opts:Slur=Upward,StemLength=0,NoLegerLines
|Note|Dur:8th,Slur|Pos:-11z|Opts:Slur=Upward,StemLength=0,NoLegerLines
|Note|Dur:8th,Slur|Pos:-9z|Opts:Slur=Upward,StemLength=0,NoLegerLines
|Note|Dur:8th,Slur|Pos:-6|Opts:Stem=Down,Slur=Upward,Beam=First
|Note|Dur:8th,Slur|Pos:-4|Opts:Stem=Down,Slur=Upward,Beam
|Note|Dur:8th,Slur|Pos:-2|Opts:Stem=Down,Slur=Upward,Beam
|Note|Dur:8th|Pos:1|Opts:Stem=Down,StemLength=8,Beam=End
!NoteWorthyComposerClip-End
On the new second staff, enter this:
