To name a node:
Double-click the node name and type a new name.
But it doesn't work for me. Is it a bug?
I have a hard time working with the FX Schematic because there's a lot of nodes and all their names read "Palett~lter 13", "Palett~lter10" etc. It would be nice if their names would not be abbreviated. Or otherwise, being able to rename or label them to "Character lines", "Character areas", "Character shadows" (also, preferably without being abbreviated) would be nice.
