Its easy to use

Great for checking spelling corrections and misused words!

From the very begin, i have 2 problems with this extension:

1. Sometimes it kinda hangs on loading. Helps to reload the page. This annoying.

2. When text line is located on the top of the page, like the first 4 lines, you can't see popup suggestions, because extension is showing them upper, where page is not exists. Extension should better calculate the position of popups to make it visible to user.
