I add internal link to some namespace page using widget. This widget insert link with text "Namespace:Page". Where is option or extension that will add link without namespace in text? Just "Page".

Visual Editor allows you to use a custom label for any link, though I'm guessing you want the label to be added automatically, right? In that case, you may be better off using the DisplayTitle extension to customise the link label for any wiki page (provided that the page exists on the wiki).
