So, still no HiDPI/Retina support. This is probably the most requested feature since at least Pharo 4, and nobody seems to be interested in implementing it.
Generally speaking unless there is a big company behind the scenes that pays the developers for an open source project, it doesn't matter how many people ask for something if the developers themselves aren't interested in working on it and your best bet is to do it the old fashioned way (yourself :-P).
