Opera 12.x has been my favorite browser for years. The decision to switch to Blink engine may be right, but old users are unhappy when they see that lots of features which they had been familiar with are lost.
One of them is that the New Opera loses the ability to open a bookmark page quickly. I have hundreds of links collected in years. In Opera 12.17, I can press Alt + B to open the bookmark page. In this way each link is associated with a shortcut key automatically according to its title. Users will quickly be able to learn how to open most bookmark links in 1 ~ 2 seconds (e.g., pressing Alt + B + V + S).
In current version of Chrome and New Opera, this is impossible. I'm currently developing a Chrome Extension that emulates the classical opera bookmark menu. But after some investigations, I found that there are a lot of limitations, and such a plugin will work but not exactly in the "opera classic" way (BTW, it will looks ugly).
Do Opera developers plan to get this feature back? If so, I think I can just stop working on it.
