Taiga-Next/Tenzu is not worked on by Kaleidos anymore, it is us at BIRU that have taken on that responsibility (see this post for details) so I’ll be happy to answer you about Tenzu :).
I won’t be able to answer for Taiga 6 however, as that is now maintained by Taiga Cloud Service.
Thank you for your feedback about mermaid charts, I agree that there are use cases where it would be practical to have it embedded and editable inside story description. We will eventually make a new pass about what to include in our rich text editor, for now it’s pretty basic so we’ll have to think about it.
If you want to reach us about any idea or feedback, we now have a dedicated community discourse here, don’t hesitate to join, we’ll be more readily available there !
