Easy way to add different fingerings to a series of notes? (Ideally want to only use keyboard)

I would vote to have the focus remain on the note too...the only reason I said to keep the other behavior was out of the principle of not breaking prior behavior. But once have nice auto positioning, then there will be no need for user to manually adjust.

Best to have someone who actually uses figuring implement it...so that rules out the pro pianists like yourself :)

I am doing a bunch of manual penciling in of fingerings on my keyboard part right now (I gave up using musescore to finger because too slow). The basic rules I found when placing the fingerings I found were:

1. if *any* note of the chord is overlapping the staff, then the fingerings should be stacked above the chord
2. else (i.e. only if all notes of the chord lie outside the staff), then the fingerings should be to the left of the chord. If there are accidentals, then all fingerings of the chord will be placed just left of the leftmost accidental.
3. If some noteheads are left of the stem while other noteheads are to the right of the stem, then the fingerings for the noteheads to the left of the stem would be offset left by the width of the fingering text (so don't have numbers overlapping when fingerings are to the left of the chord, and so that shape of the stacked fingerings matches the shape of the chord).

I have no idea what common practice is, though. Also I think should be some option in preferences to force all fingerings to be above the chord, or to force all fingerings to be left of the chord (even if overlap staff).

I'm thinking as far as inputting a stacked chord goes, I would say if user pressed more than one number before pressing the spacebar, then the fingerings will be treated as stacked. Pressing spacebar advances to the next chord (like how lyrics input works). Of course this only works if stick to the number 0-9 only for fingerings (i.e. only one-digit per fingering).
