how do we get this bad boy merged? Willing to help in any way I can.

I am looking to manage click events in my dashboards and plotly/dash#140 seems to be the ticket.

This would likely require a multi-week effort. So, customer sponsorship can help get this across the finish line, otherwise we'll get to it when the some of the other milestones are cleared out more https://github.com/orgs/plotly/projects.

It's a large project because it depends on solving some gnarly issues with the interface design in plotly/dash#291. We need to make sure that these changes are done in a way that don't make adding other interfaces more difficult in the future.

Note that in general, click events in Graphs are going to get a lot easier to work with once plotly/plotly.js#2824 is merged. It won't necessarily help out with the "which graph was clicked on" problem, but it will help with the "click as select" or "click on multiple points" or "click to unselect a point" problem.

Closing, as I just did with its companion plotly/dash#140, as this has gotten stale and most use cases have been addressed in other ways. Please open an issue in the dash repo if you have a use case we're not able to handle well.
