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).
