You can add to the control panel any number of custom buttons that will be linked to a specific URL, and choose to either make them visible to all of your customers, or only to yourself. The buttons you create from the repository of custom buttons can be placed in any of the following locations:
You access the repository of custom buttons clicking the 
Custom Buttons icon on your Home page.
NOTE
If you wish to create individual buttons that will placed only on a specific Domain Administration page, you should access the required Domain Administration page, and click Custom Buttons.
To create a new custom button, follow these steps:
When on the Custom buttons repository page, click
Add New Button. The Custom button properties page opens.
Type the button label in the Button label field.
Choose the location for your button.
Specify the priority of the button. It will be used by the control panel for defining the button layout order in cases when there are several custom buttons on a page.
You can use an image for a button background. To do this, type in the path to its location or click Browse to browse for a file. It is recommended to use a 16x16 pixels GIF or JPEG image for a button to be placed in the navigation pane, and 32x32 pixels GIF or JPEG image for buttons placed in the main frame.
Type the URL link to be attached to the button into the URL field.
Using the checkboxes, specify whether to include the data, such as domain id, domain name, client id, company name, client's contact name, and the client's e-mail to be transferred within the URL. These data can be required for processing by external web applications.
In the Context help tip contents input field, type in the help tip that will be displayed when users hover the mouse pointer over the button.
Select the Open URL in the Control Panel checkbox if you wish the destination URL to be opened in the control panel's right frame, otherwise leave this checkbox unchecked to open the URL in a separate browser window.
If you wish to make this button visible to other users (sub-logins), select the Visible to all sub-logins checkbox.
Click OK to complete creation.
Once a new button is created it appears in the list of custom buttons in the repository.
To change the properties of a button, select its label in the list. Note, if you wish to make a button visible/invisible to other users (sub-logins), you can simply click an icon in the A column of the list.
To delete one or several buttons, select the corresponding checkboxes, and click Remove Selected.
