Ok, a good update: it's easy to remove these elisions. I'll keep using UNREPL for now, because it makes easier to break evaluations and to eval commands, but it's on the roadmap to also remove it. In the meantime, rendering is now faster than the old version. There are still some (maybe lots) of edge-cases that I need to take care of, but at least some of the weird things that happen when trying to customize code will be completely removed on the newer version
