@pearl-victoria yes man it's really annoying to click on tab then switch everytime you wanna switch tabs why they not adding basic features like this and true amoled black theme after repeated requests from community come on opera developers
The reason there is currently no "Opera browser for IOS" (to correspond to the full name of the Android version) is that Apple does not allow alternative rendering engines on the app store. That is, Opera Touch for IOS is required to actually have Safari render the web content, the differences between Touch and the native version of Safari being the user interface and My Flow. I'm sure they could do an IOS browser that syncs to Opera desktop versions and is closer to the interface used on Android, but other features of the Android version couldn't be implemented on IOS.
When you go to Yandex, or Amazon, or Ebay... there is a search box you type what you want to type. If you long press that box, Opera pops up an option for you to create a search engine using that box. You can add Yandex as a search by that way.
Do you mean, name it to a constant name, so that only a single file will be stored, because there is a replace option? That's a very clever and useful idea, thank you:) Still, integrated pdf viewing would be quicker anyway. From now on it would't be as crucial, but I would appreciate if Opera could add it during their spare time:)
