Hello,
I would like to be able to add some UML to document ideas on Meta. I'm already familiar with PlantUML and there's a Mediawiki extension for it. Thus said my main concern would be to have a solution that enable to generate this kind of diagram and in the same time editable on Meta.
I see that the PlantUML extension states:
This extension is currently not actively maintained! Although it may still work, any bug reports or feature requests will more than likely be ignored.
So I'm not sure it will go to production in such a condition. 😆 But you are sure to have nothing if you don't even ask.
If that is not the appropriate place to submit this kind of request, please provide me with proper information to where I should better go directly next time. 😉
