Description
Bug description
'Tools/Regroup Rhythms' could use some improvement with how it handles note values smaller than quarters. This feature is especially helpful for beginners without much engraving experience, and for quickly reformatting notes after input.
See the example score (attatched below) for instances where the tool makes some errors. Change the extension to .mscz before opening.
regroup_rhythms_mistakes.zip
Steps to reproduce
- Create a new score
- Input notes with no regard for rhythmic spelling
- Apply 'Tools/Regroup Rhythms' to the score
- For more complicated rhythms, notice the errors

Trace the implementation of that tool and compare its output with the examples, including eighth notes and smaller values. Done means the incorrect regroupings shown in the score are corrected.
