[Fingering Placement] Implement "Auto" VS Explicit "fingering above/below"
Fingering placement is automatically decided by the properties of the staff and the chord it's attached to, and the decision is the same as expected on most occasions, it's similar to articulation anchor. While articulation anchor setting in the inspector has "Auto/Above Stave/Below Stave/Above Chord/Below Chord", "Auto" as default, fingering placement only has "Above/Below", and the default depends on whether it's actually above or below.
Currently, fingering placement is a styled property, but because the default is not a constant, it leads to issues like #288372: S button beside "placement" property of fingering resets the property. The style of fingering placement cannot be customized, even if the user wants to. If "Auto" exists then it will always be the default, which is more logical then having the default depending on the circumstances, and therefore the cause of that issue is eliminated.
However, there's another voice suggesting explicit "fingering above" and "fingering below", so users can decide which one to use in the first place. Due to the fact that the automatic placement gives us almost exactly what the majority of users want already, is it really necessary to separated a single type of elements into two categories?
For those of you who want fingerings to be always above/below, this idea is probably most ideal. But this style of fingering placement isn't usual, though it's probably not as unusual as, say, putting all articulations above/below the staves/chords. So, how many of you are willing to layout the fingerings in this way? Would you really like to see fingering separated into two subtypes?
Ultimately, there is an idea which applies to all cases. "Guitar music is often written with the string numbers below the staff and finger numbers above", said @edrmiller, so what if we create a separate "Fingering" style page and make the placement of each subtype of fingerings a style setting, default to "Auto", but can be changed into "Above" or "Below"? And the same three choices for the placement property of a single fingering: "Auto", "Above" and "Below", the default depending on the style setting. This can fulfill the need of almost every user, but it's also the most complicated. So, if the most of you think a simple "Auto" or "fingering above/below" is just fine, it's best to follow the approved idea.
