I just added an addSliders attribute to <graph> and <point>. I am going to assume that no one has created a document with addSliders yet. If you have, let me know and I can prevent documents with addSliders from breaking for a little while.
Assuming no one is using addSliders, then I’m going to simply rename it to addControls, as I’m generalizing the feature to potentially add inputs as well as just sliders. If I don’t hear any objections, when that change lands, documents with addControls will trigger an error.
I can easily add a deprecation shim so that addSliders will gracefully be interpreted as addControls for a bit, if someone has actually created a document with addSliders. But, I’m not going to do that, if no one has, given that the addSliders feature was just added yesterday.
