Helpful Color Ramp Update

If the current ramp node cannot be updated to support this without breaking existing materials, it would then be helpful to have a completely new node that has these features.

Color ramps is one of the most useful nodes in material editor and geometry nodes, but I believe they could be updated. I list some of the small problems that we have in it.

• Accuracy. Having accurate values is sometimes extremely hard with the ramp widgets. We need the ability to widen the width of the ramp node at least 2x to the max it now is allowed to be widened.

• Allow shift or box selecting multiple widgets simultaneously and moving them together.

• Allow changing the interpolation method for each widget individually. Sometimes you want constant interpolation and for example ease interpolation together in the same ramp. At the moment, only way to do it is to change everything to be ease and then do lots of additional widgets in the ramp. It could be a lot easier.
