Gotta give this plasticity model a try. It’s simpler and indeed may converge better, but is limited to monotonic loading.

I thought about this, and you are probably right. So I thought of creating a global setting: Hide unavailable properties. If the setting is Yes, you get the current behavior; if the setting is No, all properties are always shown. The default should then be: No.

Great, this should be perfectly sufficient. Maybe “properties” could be replaced by “modifiers” or something like that since that’s what amplitudes, distributions and LCSs do.
