@solidnerd do you have a few minutes to have another look at this PR? Or should I just do the suggested changes and have someone else review?

@Echsecutor I had some problems with my GitHub notifications in the past that was the reason why I didn't responded so fast. Everything you mentioned was done from my side. So lets meet next week and check it again.
