I like Multi Instrument and controls and mapping but it feels like unfinished.
I like to see inside transpozition line editor (in multi instrument) this behaviour as I draw it on picture. On Left side is original and on Right side is what I imagine to edit line. For example I want add another points and move it freely (only points which are inside map) and curve the line between a points.
Also, I want to show / hide grid behind a points and increase or decrease a size of grid. And snap those points on grid when moving.
And last, allow to show this window under separate window with resize possibility. On my monitor are text inside map totally unreadable.
