First, I think you should post your questions on StackOverflow rather than here. Looks like the problem is in your Java code. Maybe you should mark each item's level when...

Hi, you can create a dedicated branch for that, and raise a PR after finished.

I guess mirroring is not possible. See [Entware-ng/issues/292](https://github.com/Entware/Entware-ng/issues/292)
