Different connection shapes along with colors?

[Taureon]

Differentiating via colors is always gonna make the program harder to use for a ton of colorblind people, it may make more sense to differentiate via shapes too?

like a > for commands, or ] for conditions!

At the very least Squares and Triangles would help.

Blender's nodes also have labels, which could help, too.

[Half-and-Xat]

Since it is inspired by Unreal Engine, triangles (also bigger in size) are used for execution flow, while round pins are used for variables. I agree that variables should get a label of the input and output type as well as nodes with multiple input or output execution pins. If nodes only have one input and/or one output execution pin, no description is required (cleans up nodes a bit). But I guess something like this is planned anyway.

Is #7 the first step toward your suggestion?
