Hi McNeel 
Just want to make sure that isocurve density and the toggle switch for isocurves not being included in the prompt version of object properties (-properties>object) is just either an oversight or not implemented yet? 
I really miss being able to turn isocurves on and off (and setting the density) with a keystroke rather than scroling and clicking my way down the object properties panel.
TIA, Jakob
Hi @Normand,
I’ve logged an issue so as to remind the developer.
