I had to add compression into Mermaid live editor's URL state as the length limit was exceeded with big diagrams. Wrote this SerDe which can be extended with better algorithms in the future. https://github.com/mermaid-js/mermaid-live-editor/blob/devel...

Would you be willing to file a feature request in https://github.com/mermaid-js/mermaid-live-editor/issues ? Disclosure: I'm a maintainer for the project and the feature will be a bit tricky, but should be doable. One issue is that unlike drawio, mermaid doesn't support custom placement of nodes. We could have different style arrow popups, which could render corresponding connections in default locations. I also feel that this would be a very nice feature to have. If anyone is interested in implementing, please let us know, and we can discuss ideas.
