First of all, let’s get cleared what starring is good for. As in several fields of life, in e-mailing as well, people categorize stuff. Eg. you categorize music by genre, album, artist and even by popularity (manual or play count). You categorize files at work, you categorize letters at home, that’s why we have several drawers in our desks. But categorizing sometimes just makes a mess when you have something that could be put to category ‘A’ or category ‘B’. Of course labeling in the digital world offers a solution to that problem. The other problem, which I’m more interested in, is that there is always a category, that is signed by importance.
