- When I have an example open, I can't type any commands.
- When I open an example, I expected to actually... see an example. I'm not gonna read the wall of text. I don't even understand what this is yet, that's why I tried to see an example.

I liked this one, but it took me a while to understand, I think this page is a much better intro: https://www.tinyvolt.com/geomatic/examples/getting-started

Bug: https://www.tinyvolt.com/geomatic/examples/broadcasting-in-g... Click "Draw a single n-star" Results in a message popping up "unknown command: n-star"

  You have to load the extension, the instructions are in the text above the button.

Clean implementation. One thing I always look for: how does this degrade when things go wrong? Good error handling is what separates weekend projects from tools people actually use.

  As an adult, I now write clean error handling first thing.
  The person it benefits the most is the author, when they are building it and the errors-per-use are as high as they’ll (hopefully) ever be.

Cool idea but not very mobile friendly it seems.

Pretty cool. Curious, why a one time payment? Why not, say, a smaller monthly payment?

  Not OP, but for me personally I’m tired of subscriptions. I’m grabbing the one time payment before OP changes his mind.

  Not a fan of subscription hell myself, I plan to use one-time payment for all my products. Implementation wise one time payment is much simpler than setting up smaller payments that cap at a fixed amount.

What is autodiff?

  Automatic differentiation. For any DAG with a scalar output, it allows calculating its partial derivative wrt the input parameters.

    I don't understand what the use automatic differentiation for in this context.
