Accidental placement for chords

The placement of accidentals for notes in chords is generally acceptable except in one instance: When the chord has notes separated by a half step and the notes both have accidentals, the top accidental gets "buried" in the pocket between the notes. This can be seen in the example at the second beat of measures 22 and 26. The flat is too far away; the sharp is too close. This anomaly would be easy to rectify if the accidentals could be moved around with a mouse or arrow keys.
