I find a class in the package named SignalEmitterInspector inheriting MarkerInspector. It seems that this class is controlling how to draw a signal emitter. Sadly, we have no access to that class and its parent so that we seem to have no approach to change the display of our custom SignalEmitter.
In addition to that, owing to our enormous number of signals, when we need to select a certain signal from the large list, we tend to search for it for a long time. I’m just wondering if there is a way to redraw the custom SignalEmitter along with the default inspector using some tools like odin.
