Hey there,
maybe this question is a bit obscure, but this is the third time it would be useful - might you implement the possibility to use PHP in the title?
Example: I am using the qTranslate Plugin for a Multilanguage blog - with putting
<?php
if(qtrans_getLanguage()=="de") { ?>
Das deutsche Widget.
<?php } else { ?>
The english Widget.
<?php } ?>
inside the content it is possible to create multilingual widgets without even touching the theme. But with
<?php
if(qtrans_getLanguage()=="de") { ?>
Der deutsche Titel
<?php } else { ?>
The english title
<?php } ?>
in the title-field it would be possible to fully internationalize Widgets without touching the theme.
