User testing suggestions

[JeelRajodiya]

Suggestions from User 1:

• ctrl+c on examples copies the whole text, not just the selection #53
• there is a "let's move on the next step" button, it would be better to have some happy celebration / sharing the completion button (on social media)
• minor: at chapter2/lesson2 the order is different in the left and right side ("postalcode, phonenumber, countrycode", vs "phonenumber, postalcode, countrycode"), would be good to adjust
• Feature: Prettify code in the code editor #77
• The "next" button is a bit misplaced, but you can get used to it.
• better validation error messages would be good

Suggestions from User 2:

• since we have tooltip for alt+enter, there could be tooltips explaining alt+shift+f and ctrl+space as well
• when clicking "view solution" it could be more visible how is the correct solution different from the user-entered solution (diff-like view, like in the task descriptions)
• alignment of the "next step" could be better
• the Next button doesn't have a minimum size, it becomes too small when resizing the window
• at the schema references lesson, the task can be successfully solved without using $defs (I think this can be aided with a validation schema)
• at step 6/2 the editor yielded an error saying "Unable to load schema from 'https://json-schema.org/draft/2020-12/schema'. No schema request service available"
• at the top of the page, there could be a Next button, similar to the Back button
• give proper text color to a completed task and active task #76
• in chapter 8, the Title and Description are in capitals (which is not consistent with comment, default, etc) #75
• chapter 8 / task 4 accepts any "format" value, not only email
• Update UI to show appropriate feedback on the clearing the progress #84
