After creating an account, I was looking for some kind of icon where I could change my profile picture, but there was nothing found. After hovering my mouse around things, I found a small rectangular space which appeared to have the user configurations (see image below).
The white rectangle next to the magnifying glass and list buttons is the user icon.
Expected behavior: For some kind of icon the same size as the others indicating that this is where you go to change your user stuff (maybe a generic profile pic or the first letter of the user’s first name, something like that).
Hope that helps, great community site so far! Cheers.
