1) You can translate article, menu, categories and more from only one page(component); copying layout (images, charcater, type...) from original language (so more speedy respect original joomla system where you need copy and rewrite all content)
2) Free version have only a little link at botton (but in any articles)
1) Create translation require backend access
2) Link on bottom in any content (for free version)
In any case good component! Great works!
Five star when allow translation from frontend standard form (an amazing features will be possibility to translate from original joomla input article's forms in site frontend)
