Greensock CustomEase uses SVG format now. It doesn't support Greensock CustomEase anymore.

Yeah, the easing here really needs an overhaul, including a tool that isn't external. It's a long term goal, but in the short term I should be able to make sure it allows for a very basic easing method, so that you can generate it however you want.

Has this feature been updated, since the last response to the thread? I'm also interested in the custom ease feature for the particles

While I have learned more about bezier curves in the course of my work, I haven't had the time to make any changes - the whole editor needs a rewrite for several reasons. However, the editor should accept a function that takes a number from 0-1 and outputs a number of your choice as an easing method in the config. You wouldn't be able to save it in a JSON file, but you could modify the config at development or runtime to insert a function.

// a function like this
function roundEasing(time) {
    return Math.round(time);
}

Thank you for the quick response. Looking forward to see any updates with this feature.
