Why isn't the order timeline feature included in the new version of Flow?

I agree. In the meantime, does anyone know any other way to add a PRIVATE Note to an order in flow? I say PRIVATE, because the NOTES field is not private and in many apps, including one that we use, is visible to the customer. Because of this, we only use the notes field for notes that benefit the customer.

We though of creating tags as notes, but that would really be ridiculous and cause thousands of tags which are very long.
