there's no button (TB 17.0.2) and can't find anything in toolbar buttons menu. Even tried it as the only installed add-on.

works excellent now :)

This Add-on adds no button. In customize mode (right click on toolbar and select Customize) you should now see before the first tab a rectangle. Here you can move the AppButton ( ≡ ), or every other button, to this place. After ending the customize mode the AppButton changes to the style on the screenshots.

I hope this helps to understand my extension a little better.
