Typically when a computer takes over a task from paper base, it can be designed to emulate the task the paper did - centrally. However it soon becomes obvious that a computer can radically enhance the whole role.

In this case the "Chord Sheet", sure it's primary role is to display the chord sheet, and it does a good job of this on the whole, but I have been putting my moind in the position that is playing the song and the come to a bit where they are challenged.

Apart from solid looping of the bar(s), As a musician I would want to ensure that

A] I knew the function of the chord - Roman Numeral style.
B] I could see voicings I could a basic notated form of the chord voicing -, filtering from very basic to advanced
C] Identify any melody notes involved in the bar - perhaps utilising an improved notation window.
D] I could make a free memo, if I desired, for the bar.

I don't want to be hunting all over an interface for this. Ideally, I want to right click on my bar in question.

Generally, many right click menus in BIAB are to long and contain irrelevent items. Try right clicking on a bar, for example, and you will find no less than 27 items! This clearly needs a major redesign. Why have preferences in this menu for example? Why have preferences and display options there at all? Why have Cut and copy list at the top and insert and copy bars at the bottom? Long lists like this ad tedium to the eye. Much of this list can be binned. Toolbar Drop down menus contain such things.
I believe that optionally, in a small smart font, the chord function should be displayed either for user selected bars, or for wthe whole song. Using roman numerals something like " ii V 1 of IV, " . Right clicking this, gives options like voicings and highlights any chord tone that is also part of the melody.
