You can set Preferred Servers, which will be displayed at the top of the list when you launch Client (see Starting C-Werk Client).
To do it, follow the steps below:
In the Saved servers group, select the Server from the list (3).
Click Add (5).
Note
You can save the Preferred Servers list to a JSON file and load it to another Client (see Configuring Cross-System Client and autologon).
