Ok, so here are my thoughts on the nodes so far:
1. Instead of coloring the node itself, which could clash with the flag colors, we will color only the node's outline, as well as the backgrounds and outlines of text labels.
2. We'll explicitly label the type of node. This labeling can be turned off in the node display settings, similar to how normal directions are toggled in the 3D Viewport.
3. The fun node shapes must retire to the same place Clippy from MS Word '97 did. Instead of 30 shapes, we can use thousands of free, open-source icons for any occasion from sites like
FontAwesome.com — this is the modern way. Also, custom icons are naturally possible. As an exception and a compromise, can keep the X shape for the Null node.
Can I get some feedback on this?
Thanks.
