Use the server list menu on the top right corner of the software interface. You can select any server from the drop-down list and connect to it with a single click.
Use the command line interface of the software. You can type “connect [server name]” to connect to any server that you have configured in your settings file.
Use a third-party tool that allows you to manage multiple servers from one interface. For example, phpMyAdmin for databases or SQL Server Management Studio for SQL servers.
