@MonolithProjects Hi! When can we expect the merge? I found some interesting changes there for use that I would like to see in the master.

Maybe I should split it into multiple PRs, it got kind of large..

Yeah... I think that's a good idea. Plus I see in this PR commits which are already in Master and this makes it harder to review. Please split it and I am sure I can find a time to check it 😉 Thanks!
