Not this kind of exporting, as that would just be for sharing cards and would 
leave the original database intact.

It's not a fair comparison at all, because the 2.x db files also include the 
entire information of your 1.x history folder, in order to generate these nice 
stats :-)

Anyway, what is on my post 2.0 TODO list is a feature to archive history older 
than X months to different file. The argument is not so much disk space (it's 
2012 after all :-) ), but rather speed when syncing: the backup before sync 
take much, much longer that the actualy sync itself!

I guess you know that you can change the number of backups kept in the 
config.py file.

Cheers,

Peter
