In the iOS 18 update there will be a feature in the calculator app where you can handwrite math equations and it will automatically generate an answer in your handwriting after an equals sign. It will also edit its answer as you edit the equation. This could be a cool feature to implement into Goodnotes even if it just gives you an answer when you convert an unanswered equation into maths. Addition: adding a math feature where you can type out math equations in the same way you would type math equations into word would be amazing. I also love the idea of adding more graphing features similar to notability.
