If you were building a charting library on top of Lightweight Charts, what extension points would you expect?
I've been open-sourcing a charting toolkit built on top of TradingView Lightweight Charts that includes drawing tools, indicators, replay functionality, pane synchronization, and broker integrations.
One area I'm still refining is the plugin/extension architecture.
For developers who have worked with charting libraries:
* What extension points do you expect? * How would you structure custom indicators? * Would you prefer a plugin registry, hooks, middleware, or something else? * What API mistakes have you seen charting libraries make?
