What’s new

Fixes for custom durations in Advanced Settings:

• Durations set in minutes or hours now save correctly. Before, they were stored as seconds or shown as 0.
• Renaming a segment no longer reverts when you change another setting in that segment.
• Deleting or reordering segments no longer leaves the wrong values on the remaining ones.
• Opening and saving an imported preset no longer changes its times.
