Good, but some bugs Rated 4 out of 5 stars

Thanks for doing this extension, it is great. There is some bugs and missing features, however.

- When checking the grammar on Linux with TB24, the compose windows is resized too much, and the bottom is not visible anymore. Worst, I cannot resize it. I am not sure that resizing the compose windows to see the grammar results is so great. Maybe a popup window would be better?
- It would be great to ignore some parts of the compose windows, especially the signature and the citations.
