Rated 5 out of 5 stars

Hello, 5 stars for functionality, but there is one minor annoyance...

In Thunderbird (both 10.0.xESR and 17.0ESR), if you have buttons set to 'Icons Beside Text', the icon looks right when you place it, but as soon as you close the 'Customize' window, it changes to 'Icons and Text' (where the text is below the icon), which causes it to be much taller than all the others...

This review is for a previous version of the add-on (1.5.0.2.1-signed).
