Won't save very last edit or text in Preview Rated 1 out of 5 stars

I submitted a report of an issue a month ago and got no response from the webdeveloper.

This addon will only save the previous text and not the very last edited text.

This addon will not save text that is PREVIEWED, it only saves if in compose box or posted.

With these issues this addon is not good and not usable.

This review is for a previous version of the add-on (0.8.10.1-signed).
