Same as other Mind Map tool like MindMeister, MindManager, XMind and Freemind, I would like Miro to allow import their format.
Basically, I use another mindmap tools because of rich UI. And my company only allow us to use Miro. Then, I would like to export mindmap data from mindmeister and import it by Miro.
The best way is to improve UX in Miro. But I think it is not that easy.
Then, I would like to accept the format.
