Slur bugs !
1) Slurs can't seem to cross a page boundary.
When in Edit mode, if you have a long slur in the same page, when you move to portrait (viewing mode only), and the slur crosses the page boundary, it gets 1) cut, and 2) shortened. This is pretty bad, especially for wind instruments.
2) Slurs are not adjustable (like in MuseScore), in that they sometimes are out over or under the track, or even sometimes too close and cross over a Tie between two notes. This too is pretty bad.
Keep up the good work,
