Yes as Rich said there are node number enhancements coming in v10.0.

In most versions you can right click on graphics, choose display options (this is more memory as I am not looking at software) and set the hide overlapping text to yes. This will eliminate nodes overlapping and mixing the display. Then you can rotate around for better angle.

You can also hide nodes by range and use line number to hide/display or make parts of model translucent.

You can also change size of node number text.
