Comparison chords(= harmony) from rootcontainer between NOT rootcontainers

When i study the arrangement demo 1 example..the chord ruler seems to be unused there in the arrangement view.

So when i look at the not rootcontainers their chordprogression opposite of that from the chordprogression of the rootcontainer ..that is not possible now.

I like to see in the instrument sheet at the top a chord ruler too, from the used total chord progression in the arrangement.

Suppose i choose the Clarinet Solo Container than this container section harmony is reflected also in the chord ruler (new to program by Cognitone) into instrument sheet.

So there is than a existing chord ruler in the arrangement view and a new chord ruler in the instrument view

note: the chord ruler is not working in this demo arrangement in arrangement view ?

Strange enough the  Orchid project GPO example arrangement shows here the chord ruler ?? and not in the arrangement demo example arrangement ??.. why?

Perhaps better is to have a rootcontainer progression ( originalon full length) and under this the not rootcontainer harmony to see the chance between them.
