I have seen some similar questions but I'd like to propose this idea with a suggestion as well.
Sketching is not easy because dimensions lines and sketching lines have all the same color and size (black), at least until the profile is open.
You know, sketching is actually the first approach to the software and in my opinion should be more immediate.
COLORS can save a lot of troubles for your eyes: just a fast view and you understand immediately, there is no need to zoom, go deeper, check every line start and end to see which line it is.
Thanks for support.
