<< Am I missing a setting? >>
As things currently are, there's a red line at bar 5 on the main Chord Sheet indicating a Bar Settings change occurred on bar 5, no red line indicating no changes have been made on bars 6,7, and 8 with a red line on bar 9 indicating another bar settings change has been made. The information of Bar Settings Changes is available without the necessity of opening Bar Settings (F5) to see the status of the guitar on Bar 6 that was muted on Bar 5.
Charlie,
I see two conflicting realities here.
You're absolutely correct that the enormity of the task of coding for marking each item for each status at each bar is a gargantuan dealbreaker.
However, the original need for a Chords window view to see what/where your changes have been made remains. I run into this often & yes, absolutely, it's a bear, necessitating a bar by bar exploration trying to find what you put where, if you decide to make arrangement changes up to months or yrs later. Few, & certainly not I, have that type of memory. So a visual clue -- on the Chords window (sorry, Old Muso) would be a godsend. Exactly WHAT that clue would be would be up to the PG coders.
Charlie, I would also point out that the key Red Line visual you mention (which I use & rely on often!) has severe limitations -- whenever you make a systemic change to the entire song (time change, etc.), every bar gets a red underline! This makes it impossible to spot any bar you've made changes on. That would be one possible move for PG's coders to make -- pick an alternate color for a systemic song change that differs from a bar change. That'd be the easiest fix, methinks, & would clear up that snafu...
But, while it might well be labor-intensive on PG's part, yes, there is an absolute usr need to have a visual cue as to what those changes were you made long ago -- in some way, shape or form, as the coders see fit. We can adapt to what they come up with. But a head start would be a great boon for god & country...
