Hi Brennan we will be working on providing the ability to edit and update crafts to save them to chat histories in the next iteration for crafts. For now you can play with certain crafts like react apps and mermaid diagrams by going to the edit mode for a craft. We will also be extending the ability to edit and preview other crafts in the next iteration.

You can refer to the attached video if you have any doubts regarding editing crafts and previewing them.
