Currently, in Thunderbird, only one reminder can be configured by default.
I'm talking about reminder and not notification which is only on the Thunderbird client.
I would love to be able to set up multiple default reminders when I create an event, without having to do it for every event.
There is no extension that fulfills this role and it's a shame to be limited to one reminder in the options when it's possible to configure several in the event editor. Especially for me, who is a bit forgetful...
