Yeah, that sucks, it's much easier when you can do everything in VSCode/emacs/vim and don't have to leave your dev environment to write about what you're developing…
> WYSIWYG editor (with the addition of code-specific tooling like code editor or formatter)
…wait, what?
> Kanban dashboard (inspired by my experience of tools like Trello used in larger technical content teams to manage content production process)
But if I'm a lone dev, I have a personal kanban already to cover other things that aren't technical writing, and if I'm in a content team I have a full-blown kanban tool that handles multi-platform publishing. That often includes non-text content, so I wouldn't want to trade that tool for vrite either.
> The actual headless CMS (content delivery via API, integrations, etc.)
If there is to be any point to this, it better have really good integrations into existing documentation solutions.
Yet vrite's own technical documentation ist just outsourced to swagger's online service?
And it's not even good documentation: No description of possible errors, very little to no end point description, no description of what parameters do (or sometimes even are), … I don't think this is a good example for what the future of documentation should be.
