Add style setting for accidental tucking

MU4 doesn't add extra space for accidentals when no extra space is needed to avoid a collision even when that means the accidental tucks almost directly under or over the preceding note. This doesn't happen often, but when it does, it can look a bit odd and confusing to read, especially when trying to add other indications such as fingerings. Please see example I posted and subsequent discussion at https://musescore.org/en/node/340885 . For individual spots it is possible to add space to partially or completely avoid the tucking by selecting the accidental then go to Properties > Appearance, then increase the leading space. I would like to request a style setting that would give the user general control for how much an accidental can tuck under or over a preceding note. Partial tucking as a general setting is sure to be desired by some (I think it generally looks a bit nicer than no tucking at all) while others may prefer no tucking at all, so some way of giving setting flexibilty would be ideal. Thanks.
