The Sermon Builder Information side panel can not fully open unless the sermon builder is over 1/3 of the screen width (on a 15.6" laptop). The information panel needs to fully open even if the Sermon Builder is taking up 1/4 of the screen width. This may render the work space for the body of the sermon inadequate, but it is very rare that you need both visible at the same time. Toggling the information side panel open and closed is a lot easier than having to resize the Sermon Builder panel when you want to see/edit the sermon information.
I usually use three columns, but if I also have the Information, highlights, power lookup, favorites or other tools open in the right and/or left margin columns, my working panels are about 1/4 the screen width.
It would be very helpful if the Sermon Builder Information Side Panel could fully open when the Sermon Builder is using 1/4 or more of the screen width on a 15.6" laptop.
