Out of interest, has anyone tried changing the look of the Zorro GUI. Although it's minimal and there's nothing wrong with it, it would also be a lot cooler if the GUI was modern.

Is it possible to change the Zorro panel and also the Chart viewer if so, how?

A 'cooler' looking GUI doesn't make you more profitable, but yeah, you can change the panel by following the guidelines from the manual, see https://zorro-project.com/manual/en/panel.htm

Thank you for the suggestion, it would be best to have zorro, it's own API for UI, and than you can develop any GUI you want

Up to a certain level, you can.
