Let’s be for real -- Miro is worst-in-class for connectors among the tools I have used (visio, draw.io, lucidcharts, etc.) I spend probably a quarter of my time in a given diagram trying to coax the connectors into a coherent organization. I need the ability to do auto-routing, i.e. rearranging them so as to minimize crossing, avoid other objects, etc. They also desperately need jumps (the industry standard way of indicating that two connectors are not in fact part of the same net).
The behavior of the arrow connections is also a nightmare -- NEVER do I want the arrow to be parallel with the border of the shape it intersects, yet I’m constantly fighting Miro to prevent its picking this orientation. Which means that my experience with Miro is significantly “well, this is annoying”.
