We now have an IF usecase that lets you specify frontend and backend behavior. First you need to create a language string for your tab title. In my example we'll use MY_TAB. This should then be translated as follows.
Code:
'MY_TAB' => '[cb:if application_context="frontend"]MORE INFO[/cb:if][cb:if application_context="administrator"]PRODUCT DETAIL[/cb:if]',
Specifically the new IF substitution usages are as follows.
[cb:if application_context="frontend"]Frontend Only[/cb:if]
[cb:if application_context="administrator"]Backend Only[/cb:if]
Note those are the only two usages of application_context at this time.
