The Preferences Dialog

General Tab

Animate Zooming

If set, zooming will be animated, i.e. zoom factors and viewport position will be interpolated.

Enable Antialiasing

If set, antialiasing techniques will be used when rendering graph objects. Setting this option increases the rendering quality, but also slows down the rendering process.

Paint Nodes over Edges

If set, edges will be rendered before nodes, i.e. they nodes will always be seen at the front.

Display Tooltips

If set, the first label of each edge and node will be displayed as a tooltip, when hovering with the mouse over these objects.

Paint Details Threshold

This value specifies the zoom level beyond which graph elements will be painted sloppily. The smaller the value the farther you have to zoom out in order to see a sloppier painting.

Maximum Undo Depth

Controls how many levels of undoability should be provided by the editor. The higher the value, the more memory will be used.
