Lightning

Mozilla lightning is a Thunderbird extension that installs an adapted version of this email client's SunBird calendar.

The main features of electricity are similar to those of SunBar, at the same time you can manage a few calendars.

You can add dates and appointments by filling in the required fields by clicking on a specific date: Name, Location, Date and Frequency The calendar can be seen in three different modes: month, week, or hour.

In addition to that, Lightning Thunderbird installs a sidebar that shows a preview of events coming in this month, day, or the next few days.
