Sorry for the late reply!! I was away for a few days >o<
"take me to the source code of this" kind of addon
Do you mean something that connects between the VN window and the code editor window? o.O
That sounds interesting actually. Like, sometimes when I'm working on a function in my VNs, I would think of the pseudo-flowchart kind of how would things be, code it down (someone helped me coded the actual thing tbh), and test it back and forth between the VN and the code editor window. A tool or addon that can speed this up would be quite interesting to have!
