Hi, I'm working on in-house visual scripting system by using GraphView API. The basic features like node creation, serialization, copy/paste, undo and etc are done with cool sample (yes, ShaderGraph). My next step is "runtime debugging" feature, and it needs that read-only mode of GraphView for preventing modification of the graph in runtime. So my question is, is there any features/API for read-only mode GraphView? Thanks.
