Currently, In order to see the caret/grid lines I have to double click on a bar or choose the bar/note itself and then use Shift+N shortcut (Start Note Input).
A better and faster way would be instead of choosing the bar/note, User executes a shortcut and upon hovering their mouse on each bar it shows the gridline for that specific bar. Mouse Cursor also magnetically attaches itself to the nearest grid line and it is ready for users to enter notes.
This will eliminate double-clicking or choosing the bar/note first and then go to Start note input mode…
basically, I think it is easier to Star note input with a short cut and as we hover the mouse on different bars it shows the grids line and caret and mouse magnetically attaches itself as I go right or left.
