@ephemetoot
Thank you for this useful little tool!

Feedback: I've searched for the yaml.config file to modify the max posting age and it took a while to understand that it was created in the current shell's path.

• Could you rename the file to ephemtoot_yaml.config or something similar?

• Could you display the path of the yaml.config file at the end of the init process to make it easier?
