Send highlighted text to Email Chrome extension

I was looking for extension for several days, but couldn't find it anywhere.

All i could find is tutorials how to make chrome extension and similar topic on stackoverflow with simple code how to make the extension.

So what i did.

1. Learned some simple chrome extension tutorials
2. Took the code from stackoverflow
3. Created simple extension which uses external domain with file which sends emails.

You can download it here:

At first i have tried to make new tab with standart Gmail sender, but i failed at it. Because text in the case can be sent only by $_GET parameters, and Gmail has limits - about 2000 symbols. So it means max length of email is smaller than 2000 symbols.

Solution to this was to use external domain with sender.php.
