Added favorite books, layouts and "close all" to my shorcut bar so far. That is really cool.
Have noticed that when I hover over HCSB it gives me the text of a passage instead of the name of the resource. Discovered that it does this because I had the resource open when I dragged it up there. That is pretty cool too.
This is a great way of COMPLETELY CUSTOMIZING what shows up on toolbars and saves space.
