It would be great to have the possibility to comment on a group of elements.
And make it visually clear in the interface, which elements the comment effects.
In this way it's more clear which elements are part of the comment and as a bonus you can easier comment on large pieces of code.
In the same way comments are usually done in traditional coding, like (e.g. in javascript):
//Start of function / piece of code
/* Initialize and invoke a the greetUser function
to assign user's name to a constant and print out
a greeting. */
function greetUser() {
const name = prompt("What is your name?");
console.log("Hello ," + name + "! How are you?");
}
greetUser();
//Start of another function / piece of code
/* Initialize and invoke a the sayGoodbyeUser function
to print out a goodbye. */
......
