Thanks for your ideas davis.
Hm, i thought about this too. And i can see where you come from. But then you will start searching in which hidden category your needed node could be. And even when it’s just one line, the subtabs are simply in the way then. I prefer such subtabs for things that you really rarely use. Panels can do the same here. And you can nail the panels that you need. That’s why i am still not this happy with just one big panel for Modify common. I just can’t think of a useful separation here at the moment.
You say that you need Fresnel often. Then let’s put it into the Input common panel too.
