This is it!

Simple translate is nice if you want to translate something to know what it means.
It is less usefull if you want to use this translation afterwards as it transforms the lines into short lines by inserting breaks. This means you then have to do a tedious work of text processing.

All I want is freely translate some words INSTANTLY/FAST, nothing more or less than this!
This work well, it become an icon beside the browser URL, I can quickly translate copied words with just one click on it!
(But I'm not sure is it a costly Google API.)
Unlike those annoying inefficiently translating whole page/selected text/open new window add-ons, such a waste of my time.

Suggestion:
The only considerable suggestion, may upgrade the window(definitely become bigger), make things similar to REAL google translate page that enable user switch/change translating languages.
Just a way to provide more conveniency. Thanks for the developing efforts.

Way better than the recommended extension! Excellent work!
