@Viktoria Michaelis -What I miss is a configuration button, so that the number of links shown can be increased...

For sure, better control over how these content-blocks display/behave on the Dash would make them more attractive ... at least to those who don't mind having yet-more choices 'confronting' them on their Admin page.

Choices & complexity are high-profile issues. Those who guide WordPress design policy get strongly-conflicting, highly-polarized demands/feedback about them. Especially concerning the Dashboard & Admin interface. There's a tendency for newcomers to be overwhelmed, and some of these just give up. Some then feel hurt, even become resentful.

Everybody is 'forced' to used the Dashboard, so the default Feed-settings should be selected with the novice in mind. For more experienced or ambitious users, plugins can provide alternative Feed-choices and assorted control-options, to virtually any degree.
