Could be better
First Version is Good.
My reasons for giving it 3 starts are:
1- English to arabic shows only the translation, no dictionary (probably with all languges)!!!
2- while browsing (safari, chrome) there is no right click shortcut to translate the selected text with itranslate.
Universal tranlater on the mac app store has both of these otions.
