Re: Impressions so far.
Very bad. They've dropped everything that made Opera different from any-other-browser in the interest of the New Shiny.
I hope this state of malnutrition is solved by waiting a couple of months, whereby:
a) The recently-evicted Opera Mail (which is still on Presto) gets its own port to Blink and is reintegrated in the browser
b) Opera Link gets reimplemented
c) Mouse-button rocker shortcuts come back
d) Panels come back (we all use wide screens now, Panels are perfect)
e) Site-specific preferences
f) Site-specific ad-blocking
g) Customizable Speed Dial
h) Customizable Discover, or a "My Feeds" alternative alongside Discover
i) Proper page zoom comes back
j) Status bar comes back
k) Customizable search shortcuts or dropdown
l) Dragonfly comes back
etc., etc. If the Mobile browser hadn't come in Beta as Kate Moss and in Final as Kate Moss and two green-peas' worth of lunch, why would I be worried?
Opera is building a totally new browser, as the faithful feared. The new, streamlined version is twice the size and spends thrice the memory. And does a tenth of the previous one. But hey, it has the shiny Facebook and Gmail interfaces!
