Unnecessary extra horizontal space added when adding accidentals or dots
Adding an accidental or dot to a note increases the horizontal spacing between ALL the notes of the given measure. Horizontal space is added even if there was enough space to begin with to accommodate the accidental/dot. Other added elements might also trigger this issue, but I haven't noticed this with anything other than accidentals and dots yet. This tends to create uneven spacing throughout a score and ultimately detracts from the quality of engraving.
A workaround is adjusting layout stretch, but this is very cumbersome.
This might be related to the issue of accidentals not tucking under/over preceding notes.

The attached file contains a several examples of this issue.
