Saves space!! but... I created a new toolbar (so many buttons, so little space) but was not able to toggle it with this new addon: Compact Menu | View | Toolbars\r\nI found a button (Buttons!) that says \"hide/show Toolbars\" and this toggled the new toolbar fine.\r\nThen I created a second new toolbar and it displays on starting Thunderbird. Couldn\'t find any way to remove it and finally dragged all the buttons back to the customize \'bin\'.

This review is for a previous version of the add-on (2.0.3).
