Four suggestions for MS 1.3
Great to see MS 1.2! Some suggestions for the next version, if I may:
1) It would be good if the Palettes had an Expand All Categories button, and if you could resize the height of each expanded category.
2) When choosing Save As for an open document, you are always taken to My Documents - it would be good for the Save As window to start in the folder where that document has been opened from
3) When you are about to enter a note, the mouse cursor always looks like a whole note, even though you might have a different note duration selected; it would be good if the mouse cursor changed to reflect the current note duration (as you press Q and W, for example)
4) When you double click on e.g. key signature or time signature, it would be good to be taken directly to the dialog that allows you to change this property.
