This is to help track the changes to update the codebase to mui5. I have replicated the same changes you did on your commit on the dev branch and didn't come across any issues! It looks good but if you recall specific issues you faced, I can spend some time investigating and figuring out fixes.

Some UI elements have been incorrectly aligned as I remember correctly.

Thank you, that helps! We should be able to see this in the code with automated snapshots. It will make it easier to make the necessary changes to keep the look exactly the same or very similar. I'll create a pull request for snapshots once I get them working with Jest!
