The Spotlight feature documented here is what I mean: https://community.bistudio.com/wiki/Arma_3_Main_Menu

Since we are allowed to alter the center spotlight through config in an addon, it would be extremely convenient if it could be made to connect to a specific server.
I'm guessing there's a (security) reason no script command exists to connect to a server, so it could for example be hardcoded in the engine to happen only with this specific Spotlight control, if the class contains a set of attributes with the relevant server details.

Example config to demonstrate idea:

class RscDisplayMain: RscStandardDisplay {
	class Spotlight {
		class MyCommunityServer {
			text = "Join the server";
			...
			serverJoinEnabled = 1;
			serverAddress = "1.2.3.4";
			serverPort = 2302;
			serverPassword = "abc";
		};
	};
};

With this spotlight shown, clicking it would join that server.
