@brsoyanvn There is a build error, could you fix it? Do you see it when building?

Hopefully, the error will go away if dereferencing is removed...

@annaveronika There is no any build error now

@brsoyanvn There are conflicts, could you resolve them?

@brsoyanvn Do you plan to finish this?

@annaveronika sorry for a delay, I was busy with other issues. I resolved the conflicts

@arcadia-devtools Ship it!
