Opera history will only reveal around 1 day of history at a time.
If I visit a new page, the bottommost link will be removed. Since Opera's limit on history is not time period, but an arbitrary total number of links, this would make one think that my total history is, for example 18 links (WTF).
However, if I hold the page down key for a long time (2 minutes straight), it will eventually reveal one more day. One day at a time. Wow.
How do I see my actual history?
