Review for Mailbox Alert by osa
Rated 5 out of 5 stars
Works great with my Thunderbird 8.0. I use it to display new email alert for infinite time.
I suggest three usability improvements to the addon:
1) Display not only alerts for last email but also keep alerts for previous 10 emails displayed.
2) Add option to mark email as read on alert click
3) Marking email as read in Thunderbird shall hide corresponding alert.
This is five star addon. Implementing the stuff I am asking about will make it 6 star for me.
