This application has been a tremendous time saver. This application is able to handle all of your connections to servers, whether you use RDP, SSH, SFTP, VMWare, or VNC. This application also simplifies management of your connections by creating a credential object, which can then be assigned to your connections for quick accessibility. To differentiate production, test and qa environments, you also have the ability to color code folders, and child objects can inherit the color.
