Thanks for the detailed feedback - a lot of the issues you brought up sadly were stretch goals that we didn’t have time to get to in the end. We’re working towards improvements in those areas (although we can’t update until voting is over!)
I think the primary improvement will be on-hover tooltips for board entities, and more accurately showing connections. Currently the directionality of connections is indicated by the line on the grid, although it’s definitely not clear enough, and has some issues with bi-directional connections that need worked out.
