Comment 6 for bug 771542

After using LibreOffice for a while, most users end up with different placement for its toolbars. View > Toolbars > Reset would imply such menu option resets the toolbars placement and customization, but it's always greyed out - I tried this only in Writer and Impress.

As a workaround, going to Tools > Customize > Toolbars > Reset has the intended effect.
