Allow modification of default for filling measures with rests
There are a number of situations currently where the default behaviour to fill a measure with rests after adding a note leads to non-standard notation. For example, after adding a dotted crotchet at the start of a 6/8 bar, the last half of the bar is filled as a quaver rest followed by a crotchet rest. However, standard notation would have the last half of the bar filled as a crotchet rest followed by a quaver, or perhaps with a dotted crotchet rest (not my favourite!). Another example is when notating a bass part for a waltz with just a crotchet on beat 1 of every bar. The bar is filled with a minim rest, rather than two crotchet rests.
I suggest that MS should allow the user to modify the grouping of rests filling a bar in a similar manner to defining beaming groups for different time signatures. So for a 3/4 time signature the default could be defined as three crotchet rests; for 6/8 it could be defined as crotchet-quaver-crotchet-quaver rests.
