[Plugin: Custom sidebars] Don't do the update!

Really useful plugin but I updated to v1.1 and had problems. Although the fixed sidebar is an easier way of dragging widgets to the sidebars at the bottom of a long list, now another really useful plugins with scrolling menus don’t work? Deactivating the pluginn loses all the information and so was left back at square 1.
