Brilliant addition! Rated 5 out of 5 stars

Should have been included as default with Thunderbird, but for some reason it is not. I converted recently from Eudora and was forced to fix errors in email messages because Eudora could not handle utf-8 properly. HeaderToolsLite addon came in handy, however that addon removes the 'replied to' arrow. ToggleReplied can easily add it again.

Small, simple, but very useful add-on Rated 5 out of 5 stars

I wanted to add the option to mark messages as "replied". The add-on does exactly that - it's very useful.

This addon works well except it doesn't work in the "global inbox" folder. The option is there to toggle but nothing happens. I have to be in the account inbox for the replied icon to show up.

Could be useful sometimes, and then perfectly get the job done!
I wonder why it is not included by default.

Great add-on! Rated 5 out of 5 stars

Thank you too for this great add-on! I really needed the option of marking a message as replied. This add-on works perfectly with TB 10.0.

I will never understand why Mozilla doesn't implement such really little useful functions instead of implementing more and more nonsense things.

This review is for a previous version of the add-on (0.3.3).

Thanks. Version 0.3.3 works fine with TB 6.0.1. It's just what I need to mark selected TB messages as 'Replied' or 'Forwarded' after the replying or forwarding was done outside Thunderbird (using webmail while away).

This is a fantastic no-nonsense add-on that does exactly what it says it does.
