It seems fine. However it lacks the management of "Reply all". So, for example in my case where I want to have only icons in the toolbar, I have them for all of them except for "Reply All" where there is the icon+the string.
Beside, I would like to know if it is going to support Mailredirect extension as soon as it will be ported to TB 78.x. Tnx

This review is for a previous version of the add-on (2.0.7). 

The first goal of this extension is to reproduce TB68 functionalities. So, customizing for each button is next step.

Buttons added by other add-ons are already supported.

Thanks a lot for this extension !!
I'll give the fifth star if you add capability to insert space or vertical separator between buttons, as it was feasible in old versions of TB.

And as already written by Philoppe : Why TB removed it ????

Fifth star added ! Thank you for very quick answer, and I apologize to not have seen it myself !

This review is for a previous version of the add-on (2.0.7). 

You can add space and separator. Click the Space and Separator buttons in the customize window.

Great add-on, I really wonder why this is not factory built in TB. Many thanks to the developer!
Ideas:
(1) It would be nice to have an option to align left the buttons as well (mine align to the right)
(2) It would be great to have the "unavailable functions" in a message (such as "Smart reply" when there's just one recipient) being greyed-out instead of removed, so that the order and placement of buttons doesn't change from one message to another.

Thanks again!

Really perfect re-implementation of this missing/removed feature in Thunderbird 78 using the collapsed="true" attribute. And the best is, that it supports other extensions, which add buttons to the toolbar (like my "Allow HTML Temp" addon).

I recently upgraded to Thunderbird 78 and suddenly the message buttons were all in the wrong order. When you're used to clicking in a spot for a button, having it move is very disconcerting. This add-on is what I needed to set things right again.

It's not a complex add-on, but it does exactly what it needs to do.

Excellent and does what THunderbird 78 should have given you "Out of the Box". Having labels on the header is just unnecessary visual clutter. I want to support this add-on with my SmartTemplate Add-on so that we can choose a form letter from the write / reply / forward buttons.
