About this Add-on
Extension to Thunderbird/Lightning calendar. Adds darker borders to repeat events to distinguish them from single events.
Repeat Borders adds darker borders to repeat events to distinguish them from single events.
These borders appear in all calendar views (day, week, multiweek and month views).
When a repeat event is created, a solid darker border is added to all occurrences of the event.
If subsequently, any of the occurrences are edited individually (rather than all together), then on those occurrences the solid darker border is replaced by a dashed darker border.
A similar facility is provided in the 'Calendar Tweaks' extension (also by DW-dev) using icons rather than borders.
