Good Idea, certainly handy. Bug Report - incompatible with "Grab and Drag" extension.This review is for a previous version of the add-on (1.1).
It appears that all extensions which are shown in the statusbar are fixed, that means the cannot be moved. I chose this place for my extension to show up because it is a mainly passive extension only used when you press the shortcut keys and/or click the button.
