Quick Connection Switch

Quick Connection Switch drop-down on the toolbar combines 3 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 empty environment you can choose any connection from Quick Connection switch drop-down to create an empty document with appropriate connection.
You will find fine-tuning settings of quick connection switch drop-down under SSMSBoost Settings->Preferred Connections
