You also can make an option for a transparent shortcut tile to opera browser so as to be pinned on the start screen.
You can set transparencies too for at least a part of the UI's buttons and settings.

Please improve the smoothness while scrolling up and down,
improve the user interface and make it more coherent with the Windows phone style,
add option so as to set by default the desktop or the mobile view for websites, and
add option to go to the next or to the previous visited page by flicking to right or to left.

Another issue is Opera Mini's lack of support to Windows phone's word and text suggestion function while typing, the very same typing exactly as I am doing right now at this very specific forum.
I also discovered that whenever I tried to edit my posts in this forum using opera mini, it needs to reload the webpage first, before it opens the side panel with the options 'edit& flag'. A bit fussy, and not happening with other browsers for WP.

I kind of dislike the Opera fonts being used in the webpages.
I also dislike the fact there is no auto-hide function for the buttons bar at the bottom of the screen.

The UC browser has managed to present a full screen webpage result in its interface, why not Opera too?

Another nice addition from UC Browser I would like to see here too, is the in-app rotation lock as well as the swipe to the right or to the left so as to move to the next or the previous page you 've visited.

Another suggestion is to add an option so as to pin Bookmarks as shortcut tiles in the start screen,

and why not to give those tiles the option of being 'live tiles' (i.e. pinned tiles which are able to present relevant and lively updated information on the webpages they are related to).

OK Today's update made Opera stable again.

Please add in Settings an option so as to view, by default, websites in either mobile or desktop view.

Also I have to insist on the browser's User Interface. It is ugly if you ask me, or at least it does not comply at all with the Windows Phone UI style rules. I do get it that Opera needs to stay close to its own graphics interface, but this result presented in its WP beta version is totally out of order.

Being myself for a longtime an Opera - both PC and mobile version - browser user in the past, even if I personally have been used to apprehend Opera browser's PC and mobile versions interface, this time I find myself stressed to use Opera's graphics and interface in such a non compliant environment as WP one is to Opera's.

I think everything should be reassessed in this very first Opera WP version, including the fonts size and type (Segoe fonts much preferred), the colors and their gradients, the styling of the tables as well as the icons implemented (shapes, colors etc in a wholly flat-needed minimal clean design) etc. This does not necessarily derive in something irrelevant from Opera's appearance guidelines but only an adaptation to the Windows Phone environment so that the user won't feel strange that much.

Thank you.

My very first impression on the beta version I have tested is unfortunately not that encouraging
since there are unexpectedly quite a lot of stability issues even for a beta version.

Not only am I talking about lack of smoothness, but also as everyone reports too, the browser keeps on crashing, either in the beginning or while one is trying to access several websites .
I believe this issue will only take time to be fixed, so I won't insist on that.

Another argument I have lies on the browser's User Interface.

I have to say I would expect more from what appears to be this Opera Mini WP beta version.
I strongly believe that the User Interface should be much more adapted to the Windows Phone appearance.
Please do mind.
