Diary with history integrated with Firefox & Thunderbird - is there one?
 

I use Reminderfox with a common file to have a full reminder and calendar service in Firefox & Thunderbird.

The problem is that I cannot go back to see what happened in the past (I need to keep a record of journeys, visits, etc). There seems to be no way that this can be done in Reminderfox, which is perfect in every other respect!

Has anyone come up with a way to keep history in Reminderfox, or is there another solution?

Thanks in advance.
