Works great, but a strange behavior from a few versions back Rated 4 out of 5 stars

I have been using this addon for quite some time. (One of the mail gateway through which I forward an e-mail
occasional hiccups and send duplicate messages, and thus I need to use addon like this.)
This addon works fine and quite fast.

However, since a few version back, I have noticed strange behavior.
It used to be that if I am looking at the latest messae in a folder, and
if I try to remove the dupes in that foloder only, after the removal of duplication, the
current focus (of the messages, that is) is near the latest message in that folder (module the
deleted message.)

In the current version, the focus is left on a very old message. Thus, I am left in an old message in my folder and
have to scroll down to get to the latest message. (Yes, I keep the latest message at the bottom in my usage.)
This has been noticeable since early summer(? I am not sure). But this pesky behavior is a little
irritating.
Otherwise, I will give a five star :-)
Thank you for the great addon.

This review is for a previous version of the add-on (0.3.5).
