Mesh tool hold and drag
When we click a shape with the Mesh tool, a node gets immediately applied to the shape/mesh, a new row and a column get instantly inserted. If I keep holding the mouse button / pen, it won’t help me anymore to position my node precisely. So the insertion should not happen immediately on a mouse click, but on a mouse release, drawing all the possible results while the button / pen is held down.
