This blog post shows how to build a text view which allows inserting markdown text and the result will be formatted, with headers, links and images.
.. in which we look at how to manage the versions of packages used by a Racket application, and ensure that the correct package versions are used when building the application.

In this blog post we’ll look at how to build an actual GUI application around the game mechanics: we’ll keep score, increase difficulty, peek at the next block and more.

Other questions start to become important: were some tests inadvertently disabled? which tests were skipped? how did the duration of a test evolve over several versions of a program? Existing build platforms, such as Azure Devops, can help with test management, but in order make use of their features, we need to extend the Racket unit test library to report the test results to the build pipeline.
