I love the new version of the Opera web browser. If my memory is correct (it sometimes is) I have been using Opera for about 8 years. They do like to change things up, innovate and think differently. This is often for the better, giving us new and exiting features, for instance the Speed Dial. They changed up a lot of things for version 11, but there is one change I did not like: hiding the URL parameters.
I found a solution for this problem in the opera.beta newsgroup, and it is dead simple: enter
opera:config#UserPrefs|HideURLParameter in the address bar, uncheck the highlighted field and press save in the bottom. Done. Now URLs will not be truncated in the address bar!
