I’ve been debating this over and over in my head whether I want to add such functionality or not.

The main argument against is basically that your “favourite” anime should be your top rated anime and therefore automatically appear as the first items in your profile page.

However, aside from the informational aspect, the design aspect is also important. The “favorite” anime can be displayed in a different way somewhere and therefore be nice to look at.

So there are two sides of the coin. I’m 70 : 30 towards implementing it. Added it to the todo list for now.
