Quick Connection Switch

Quick Connection Switch drop-down on the toolbar combines three useful features originally missing in SSMS:

Quick connection switching in SSMS with SSMSBoost add-in
  • Allows switching between Preferred connections
  • Keeps track of Recent connections
  • Shows all or ACCESSIBLE-only local databases

If SSMS starts with an empty environment you can choose any connection from Quick Connection Switch drop-down to create an empty document with an appropriate connection.
To perform fine-tuning of Quick Connection Switch drop-down go to SSMSBoost -> Settings-> Preferred Connections
