Mermaid charts are really useful for quickly making diagrams which are valuable for explaining definitions of success, issues, or illustrating any point really.
It is very widely used and is already supported by jira, huly, github, gitlab, googledocs and more.
I think it would be a great addition to taiga, currently I am making mermaid diagrams, converting them to png and adding them as an image but, even ignoring these extra steps, it is not as good as being able to use the mermaid syntax in taiga directly.
Mermaid blocks are easily edited by my team on task descriptions so we can update them collaboratively as our plans or understanding develop.
