translate widget

So i discovered how to translate title and texts of the widgets.
This is really important and i don’t understand why nobody speaks about this problem.

FOR TRANSLATE TEXTS OF THE WIDGETS:

<!–:en–>My English Title<!–:–><!–:fr–>My French Title<!–:–>

FOR TRANSLATE TITLES OF THE WIDGETS:

[:en]My English Title[:fr]My French Title
