it would be nice if you could define as a preference if you would like to receive a warning when you want to remove a computed text. a similar warning as when you want to remove a field.
a lot of functionality is build in computed text and it ...
In Eclipse based designer, there's an option "Show warning when editing design elements that inherit from templates" to control the warning. But actually there are two warnings if the option is checked and STILL ONE persists after it's not checked.
