When using Cycles and editing materials, the user is presented with a button called Use Nodes. This is confusing and adds an extra step before being able to set up materials.

It might be nicer to simply have the material use nodes always. Materials without nodes doesn't even really make sense when using Cycles as they are central to material editing and creation.

The reason this button exists is that when you press it, the Blender material gets changed. It converts a non-node material to a node material, and doing this automatically when you switch between renderers would break materials. The rule is that switching between renderers with the menu will not actually change any data, it should be possible to switch back without any data having changed.

If you add a new material it will automatically use nodes, it's just for existing materials that this button exists. I'm not to happy with the fact that it's there, but I wouldn't know how to solve it well.

@brecht: I guess this is one of those things that's mitigated with setting Cycles to the default renderer. This way, the button will only appear on old blend files you'd want to convert to Cycles scenes.

Right, well almost. I still need to figure out some better way to signal Blender Internal not to try to use Cycles nodes, otherwise switching to Blender Internal with the default startup.blend all the materials would be broken, which seems doable.

@brecht: Yes, that'd be nice. It could be considered a showstopper for switching to Cycles as the default renderer.

Switching back to BI should work without making everything invisible :)
