After using/checking everything of this new opera mini 8, here are my opinions/suggestions about it.
There are now altogether 4 kinds of opera (mini) available for androd. So, it could be confusing for some users to decide what to use. Can't we terminate old opera mini 7.6?
My most favourite and useful layout is classic, everything is good there but cancellation button (×) which is in adress bar is little bit difficult for one-hand user. You should have added that button (×) in bottom of layout integrating/combining with forward button (>) as well. It will be more easier for quick cancellation in accidental clicks.
Green connection progress line under the adress bar is little bit thinner/slimmer and difficult to identify. It should have been a bit thicker.
In text box we can not copy all text like before.
