Hi @NeffIsBack Did you get chance to review the PR?

The code looks good so far, but due to the enormous amount of Pull Requests in the past there is (un)fortunately still a huge backlog of PRs i have to test first before i can test this one. Bare with me, the day will come

Hi @NeffIsBack! Any updates?

Unfortunately not, there are still ~25 PRs left before this one.

However, it looks like there are merge conflicts on this branch which anyway have to be resolved first. Also, i don't have permissions to update/push commits to this branch. Did you change any security settings on your fork?

I havent changed security settings on fork but anyways, I have resolved the conflicts.
