To be fair, this is a monster which has been fed for decades by very different people. And me, as newbie as I am, can't brag about doing this much better. Well, maybe a little better, as I can at least see what is obviously wrong. But this does calm the impostor syndrome a bit, so everything's fine. ;)
Anyway, I'm incredibly happy with $newJob, really enjoying the workplace and colleagues. And, better or worse codebase, I'm really having fun playing with it. :D 2/2
