In addition to document tabs in the application frame window, the status bar of the Object Explorer tree also changes its color based on a connection of the object selected in the tree. For example, when you select a table in the Tables folder, the explorer’ status bar changes its color according to a color, which you selected for this table’s connection. It makes it easier to see on which database the selected object resides in situations when the Object Explorer tree has a large number of nodes and it is impossible to see the parent's Informix connection folder without having to scroll the tree.
To define a color-coding for Server Studio connections, choose Tools - Connection Manager top-level menu. In the General tab of the Connection Manager window, choose a required color in the 'Color for a connection's tabs' dropdown listbox and press Save button to change this setting. If you want to change a color-coding for a different connection, select a required connection in 'Connection' dropdown listbox.
To remove a color-coding for a database connection, choose 'None' from 'Color for the connection's tabs' and press Save button.
