I use Mermaid to visualize all sorts of processes, so this is very interesting.<p>Some immediate feedback:<p>- ability to name the node ID, because now the Mermaid output is hard to read and edit<p>- more shapes (diamond, circle, etc.)<p>- text on connection<p>- shortcut to connect with a node after one is staged for connection (didn't find one at least)<p>- ability to select connections with keyboard<p>- shortcut to delete the selected connection (now you need to click Disconnect, the shift+delete doesn't seem to work)<p>The layout gives me Excel vibes: what if these nodes could export values and do computation? Like, the Apple Income Statement example, but dynamic. This combined with an ability to export a snapshot as a Mermaid diagram, it would be great to explain business cases, etc.
