Thanks for your feedback @brianwjagger – this has been mentioned before, and I understand how this could be beneficial.
A couple of the reasons for why it doesn’t are:
- when the duration is a whole note, there’s no way to identify the voice direction into which you will input notes (which is one of the key reasons the symbol is there in the first place)
- there are many durations that would be complicated to notate beside the caret (crotchet tied to a dotted crotchet, for example); although it’s generally “simple durations” you can select in the panel or using key commands, if you start note input with an existing note selected, its duration is then set for the next notes you input.
- if the symbol indicates a dotted crotchet, but because of the note’s position in the bar and the meter, the note you input gets notated as a crotchet tied to a quaver, you might think the symbol was misleading
Here’s an earlier thread in case it’s of interest:
