Ayespy, as a follow up of our conversation on one of the Vivaldi blogs, it looks like Vivaldi is mode with many web technologies, some of which include: React.js, Node.js/node-webkit, Polymer, and a ton of others. If you look at node-webkit, it's the former name of NW.js, so it looks like Vivaldi is most likely using NW.js.
Now, I'm hoping that eventually, Vivaldi will be able to strip Chromium code they're not using, that they're already using their own stuff with these web technologies, and become independent and control their development. But anyway, I'm pretty sure they do use NW.js.
One feature I really like (possibly the only one) is the quick "set these tabs aside" feature. It's somewhat like sessions, but easier to use as it creates what is effectively a temporary saved session.
Posts like the OP that are negative do clutter the forum. Inevitably, people respond and a few more kbytes get lost in cyberspace.
If, after six months, you have not discovered any bugs, thought of any feature requests, nor asked any questions about how to use or modify Vivaldi, then you won't miss being able to post. I suggested 6 months as a reasonable limit because I know that people don't immediately get around to testing new software that they installed just to try it out.
Those who just want an email address are welcome to keep it. I don't think it would be hard to purge forum membership without also letting users retain their email address.
@Pesala I had to think about how to reply to this, I don't want come off wrong, since you missed everything that @luetage mentioned and I don't want to start an argument, yet another reason why people don't post in forums. It's quite frustrating watching someone defend their opinion rather than looking at facts and how it will effect someone other than themselves.
You've been here 4 years with 4k+ posts, I've been here 2 years with 8 posts, and I only started posting recently. I was subscribed to many topics before I posted anything. I still don't have much time to post, you know the usual, work, family and real life activities which I enjoy a lot more than being on a forum but I still enjoy reading forums. It's not just about the email, there are more perks to being a member, look at @luetage post above and see what he already listed.
All you can do is report the post and it can be deleted if the Mods see fit. Even trolls change sometimes and start contributing or at the very least provide entertainment. It's the spammers that are the real problem, like the one we had this past month posting in Chinese in all the forums.
Err... the title of this thread was about Opera Mini, but the link provided although the title also about Opera Mini the content seem about Opera Desktop or probably Opera Mobile (never use/test this one).
So, either me or that blog content was wrong.
Opera Mini does have "clear private data".
