Useful tool , some suggestion!!! Rated 5 out of 5 stars

It's every useful tool. but the sidebar is standalone , it no so good, it will make some collision work with other sidebar addon.
why not put the sidebar into the browser sidebar frame and menu, it more easy manage specifically when using other sidebar addon.
and if add a toolbar button and add a option to choose show or hide sidebar stick will be better!
