Store loads of buttons Rated 5 out of 5 stars

Like it very much because it gives a lot of extra button storage.
Since I use a lot of extensions, and I have loads of buttons for which I have no room available, all extra Toolbars are welcome.
So I would like this even more if one could install more (vertical) toolbars at the same time, this would create even more button storage.
Even better it would be to put ALL the available buttons in a Toolbar from where I can drag them to other toolbars. Then one could already use the available buttons.

This review is for a previous version of the add-on (0.2.4).
