Rated 5 out of 5 stars

Very nice add-on, thank you!!!

I have two feature requests, though:
1. It would be perfect if the linked messages are displayed right away, when I click the message title in the "tasks&mails" panel. Generally, that's the first thing you want see: Which messages are linked to this task.
2. It would be nice if the filter "show only messages with tasks" wouldn't display tasks, which are done already. If you are working with the add-on for a while, you have hundreds of tasks done, but you don't want to see them when you want to have a overview what's still to do.

It also would be nice to have a German translation. I could offer to translate it..

This review is for a previous version of the add-on (2.0). 

Good suggestion and Ok for german translation

Thank you !

I was looking for a volonteer that would want to make the german translation, I think I have found him :-) Give me an email and I send you the files.

I take note of your suggestions. For the first one, I think you have to activate the filter "show only linked messages" and the filter "show only linked message to selected task". Then, when you will click on a title, you will see only the right messages. I can make these filters persitants if needed.
