It's a great Addon.
-The translation box needs to be floating, rather than immovable in the BR corner.
-The copy button should copy the ORIGINAL text to the clipboard, NOT the translated text - this is because Google often messes up Japanese/Chinese and as you don't support Romanji and Pinyin then the user needs to copy the original text to Google Translate directly so as to see the pinyin/romanji.
- Macro key options are limited to the F keys and A-Z (!)

- translation box is floating when used for inline translation
- I don't see how copying original text is more useful than copying translation. Original text can be easily copied with normal OS functionality
- Didn't really understood this one, short cut keys are not limited, and can be combination of any supported keys
