hey :))
IMHO this would be of great help to be able to drag mouse over the nodes previews and see the RGBA values.
in a [0;1] way or in a [0;256[ way.
the visual is… just wonderfull but the math is mandatory when you’re dealing with… maths 
regards and happy ShaderGraphing ^^
Shader Forge did this up to any node that wasn’t a vector. As in you could multiply a vector1 by a vector4 and you’d get 4 numbers underneath the multiply node, but if you added it to the normal direction (or something based on geometry, usually shown as a sphere) it’d not show any values from there on out.
Useful for sanity checks when you’re doing a lot of math that gives answers outside the 0-1 range, trig stuff mostly.
