Hello Maic.
I hope you are going well.
I tried to submit a few merge requests a few weeks ago.
Have you had time to review them?
If something is wrong, please tell me and I'll do my best to fix it.
Best regards.

Hi, thanks for the contribution, I was a little bit busy regarding another open source project.
I merged your two pull requests and will have a look into this one as well.

Great to see you back on this project! :)
Don't worry, I will resolve the conflicts...
I also have many more evolutions to submit...
By the way, what do you think of "black", the code formatter? I started using it on my fork... I think it's pretty good...
