@mariux this seems like a complete rewrite with untested new logic. We spent a lot of time testing the current version and made a lot of fixes and tweaks to make sure it works in all scenarios and fulfills the acceptance criteria.
I suggest at least the following, as a start:

• Break this PR down into smaller, more readable changes.
• Write a description for each change explaining why it's necessary. This will require a significant chunk of our time just to test it again so it has to be justified.

As @zied-elouaer said this is a rewrite and will require testing

@mariux pls review

[soerenmartius]

@mariux this needs to be addressed, having a PR open for ~3 weeks is too long. ty

Write a description for each change explaining why it's necessary. This will require a significant chunk of our time just to test it again so it has to be justified.

We need to have a maintainable code base. So moving things into functions and adding error checking is the minimum here.
