Vivaldi 4.0
Vivaldi Mail? That took a while :-D<p>Vivaldi is developed by a team created by the former Opera founder and CEO. Vivaldi kind of tries to re-create the spirit of Opera, but I think it's going to be too hard to do it.<p>For those who didn't use it, Opera was first a paid browser (which limited its reach), then an ad-supported browser (which again limited its reach). It then finally became a free browser but by then it was too late.<p>It had its own, super fast, rendering engine (I forget its name, Presto?). It had a built in email client, feed reader, calendar (unfortunately with no Exchange or Gmail integration), a notes app, a powerful download manager and even a Bitorrent client. And a TON of features and UI flexibility.<p>It was super compact, a marvel of engineering and UX design that managed to pack all those things in a package of about 5MB at the time, and you wouldn't even see or load the extra functionality like the email client if you didn't use it.<p>Unfortunately with HTML5 and the Chrome-ification of the web, it couldn't keep up :-(<p>Vivaldi tries to do the same on top of web techs and web techs just can't handle it. Web techs are almost as flexible but they're really slow and bulky.<p>Still, I wish them luck.
