Small addon that adds a back to top icon in the postbit. Note that the icon will not display in the first post any longer.
There is one setting for the addon. If enabled you can use usergroup permissions for which groups can see/use the addon.
There are two style properties for the addon. One controls which location you want the icon to be displayed at, before the share icon, after the share icon, after the bookmark icon and after the post number. The other property allows you to set any font awesome icon to use as the back to top icon.
The back to top icon will also show up in conversation postbit as well.
