Hi @code-incubus,
I have checked this PR and it looks OK. There is only one thing - please rebase it to the latest develop, because you are missing quite a lot commits.
After that It will be approved and merged (I can see that there was no problem with the tests).

[code-incubus]

@LeoNerdoG Done.

Hi @code-incubus,
I have checked this and now everything is OK.
@Coduz, can you please merge this after the tests complete?
