I just want to bump the thread again; these are no major requests and could be fixed within an hour or so, but they prevent me from using the parts for sets/MOCs completely.

Done.
Except for fit between 32002 and 4185. Can you post a screenshot?

Thought I should add this:
I noticed last year that the corner snap points on part 75937 are misaligned. If you look [closely] at the attached image, you can see the ones on the corners are further away the middle of the piece just slightly more than the other ones:

"Except for fit between 32002 and 4185. Can you post a screenshot?"
It's easier to just tell, I would've to composit four images in order to clarify it.
Part 32002 has a short and a long pin side. For the small openings of part 4185, the smaller pin of 32002 is used. In real life, placing the Technic pins in any hole will be done by squeezing the part together and putting it through while the slightly larger pin ends will make the part stay in place after it has left the hole; also in real life, 32002 fits perfectly in one of 4185 holes, so the slightly larger pin end will get through. On Mecabricks, I can't get the smaller part of the pin through one of the holes; if I place it so that the middle section of the pin meets the hole, the slightly larger pin ends will still be inside the hole (so it would exit in real life), and if I drag the slightly larger pin ends, the middle section of the pin intersects with the part.
