Various post-demo fixes

• The project passes automated tests locally (build, linting, etc.).
• You updated the project's documentation with new changes.
• You've linked any issue this PR closes
• You reviewed your own PR and made sure there's no test/debug code or any obvious mistakes.

Make sure that the code wasn't copied from elsewhere (check one):

• You have made sure that we have permission to use the copied code and that we follow its licensing
