Hi @MuazOthman just wondering if you still want this PR kept open?

[MuazOthman]

@ryangribble sorry for the late response, it's crunch time at work these days! Please keep this open if possible, I'll try to get back to it as soon as I get the chance.

What's left to get this over the line? Anything I can do to help?

[MuazOthman]

That would be great! The checklist above can provide guidance to what's still to do.
I can add you to my repo if you want and you're welcome to pick it up there.

@MuazOthman Are you still keeping an eye on this? I grabbed the changes from this PR and have put in some work.

Hey all,

FYI, I have a PR (#2246) that supersedes this to tackle #1707.

If you worked on this pull request, I'd welcome your input/review over at #2246.

Closing this out in favour of #2246, which should be out in the next release
