Hi, @khalibloo! Thanks again for the PR and the time and efforts you put into it. In #4518 we improved the flexibility of the core.

Could you add me as a collaborator to your fork? I would like to apply the proper changes and tests as it would be quicker and less time consuming than explaining in comments!

[khalibloo]

Sure thing, @NyanKiyoshi ! I've added you now.

[NyanKiyoshi]

Thank you! And thanks again for the work!

[khalibloo]
