As a freelancer, one thing that always annoyed me was how much time got wasted on tiny client requests. "This button should be green." "There's a typo here." "Can we move this section higher up?" "The spacing looks weird on mobile." The actual change takes 2 minutes. But then you have to stop what you're doing, pull up the project, find the right files, make the change, test it, commit it, push it, deploy it, send the client an update, etc...
