I just came from app asana and I realized that some times we need to let a comment on an image specifying some fixes that the worker (developer, designer) should do but I don't know if is possible as I have done in the other software mentioned. Into example below we select some parts from the image and we can let comments as we see (10, 7 ,8); whether we want to get more info about this comment we just need to select that number and then will show up the detail as the second image illustrates.
