I normally set up layers for guides crvs. Each viewport (top, front, right cplanes) has a different set. Yesterday I tried to use guides in place of the curves and it was just too many enabled at once. Instead of crvs tied to layers, it would be nice if the guides could be tied to the CPlane they were created on. I’m asking that it be an option, even though I cannot think of a use case (other than smart point at cplane origin) where the front guides are helpful in the top viewport and vice versa.
