The zooming option in Vanted seems a bit unintuitive because when you move the graph to the middle of the view and then focus the mouse on a node and zoom in via the mouse-wheel, it first zooms like three times to the top-left corner of the whole view and then finally zooms into the (now automatically moved) mouse position. When you reach the maximum zoom, and still try to zoom further, the view shifts to the bottom right corner. It would be nice if the zooming would be consistent so when you focus the mouse somewhere it should zoom exactly there and shouldn't change at all.
