Another case that I encounter frequently is two dotted quarter notes in 3/4; by default the first note is a dotted quarter, the second is an 8th tied to a quarter. That might be correct technically (to differentiate 3/4 from 6/8), but I find myself continually resorting to Force Duration to change the second note to a dotted quarter note. It just doesn’t look right.
And if you want to make these two notes into a tremolo, it is impossible without Force Duration.
