I do like slic3r tho. I had a few spare moments to tinker around with it earlier and it's not much more difficult to use than cura. It does however make me wonder why cura has such a hard time slicing thin objects. You'd think with how popular cura is they would have this issue at the top of their Todo list. I'm half tempted to contact them and see if they know about this issue and plan on future update fixes for it.
The devs are well aware of it. It comes up in requests fairly often. Basically the way their code works at a very low level means it's not going to happen as they'd have to more or less rewrite the entire slicing logic from scratch When I first ran into it I did some googling and found a couple of threads on the reprap forum discussing it and a few issues in their github - I got the impression the devs are tired of hearing about it and have zero interest in fixing it as they consider single perimeter walls to be an uncommon edge case that most people don't care about.
