Here is a screenshot of the latest souped-up XPresso (only, no Python) based version showing a more complex "Torus Knot (11,3)". In terms of enhancements, I've added additional functionality, automated pretty much everything, and added lots of helpful guides. I also fixed a few bugs/shortcoming in the prior version.
The following image shows all available guides just as as showcase of features. Realistically, only a few of these would be enabled at any one time depending on what aspects are of interested and/or are being worked on in related scenery, so as not to add unnecessary clutter and complexity to the knot topology that is shown.
