[FEATURE REQUEST] Add Separator (horizontal line) to custom links list

[Korb]

Current Behavior (if any)

All links are displayed in one uniform list.

Desired Behavior

The list can be divided into parts by grouping links by type.

Motivation / Use Case for Changing the Behavior

In my case, external links are divided into informational and alternative sites for obtaining the game. Now I have no way to clearly separate the former from the latter.
