I’m no expert but just my first impressions using ShaderGraph!
Custom Function
- Would be nice if you could change the name, eg. the name becomes the name specified
- Saw that creating your own nodes via Scripts is not currently possible, deprecated?
Wires
- Some kind of junction box to connect and reposition wires. Not always going left to right
- Maybe the ability to add a wire point node/dot, like when creating a bezier curve. Also useful if sending to more than 1 node (convert to straight line from a wire point). Wire point defines a straight connection, Nodes define a straight then curved connection
- Wire colour customisation, for complex graphs (wires drawn as selected colour on a palette)
Nodes
- Ability to reverse the view of In/Out. So you could create diagrams left>right, right>left, left>right
- Background colours could be dark red In, dark green Out for example (customizable)
- Or, an arrow in the middle showing the direction
- Dials would be a very nice addition to changing values (as used in complex music/synthesizer graphs). Hold both buttons for fine movement of dial
Other
- Would be nice to work on a grid / snap function. Also might then be easier for wires to procedurally create paths, eg. out>down>left>down>in rather than out>diagonally left/down>in
- Dual switch boxes. eg. In (selection) Out1/2/… (2+ processes in between) In1/2/… (=selection) Out.
Just some random thoughts for inspiration anyway
