When it comes to web browsers, if you consider yourself a 'power user' and feel that the likes of Chrome and Firefox lack certain features as a way of making them more accessible, then Vivaldi could be for you.

Working with a "team of browser building pioneers," Vivaldi founder Jon von Tetzchner - co-founder and former CEO of Opera - has set out to make "web browsers powerful again" with the launch of Vivaldi 1.0.

"There is really a need for a different kind of product in the market," said von Tetzchner. "And so we decided to build a browser with rich functionality."

Following a long period of public development, the official 1.0 version of Vivaldi is released today. It comes with a slew of features, including the ability to drop tabs on top of each other to organize open pages into groups, tab tiling and web panels that let you see multiple pages inside the browser at the same time, a note-taking tool that supports images, and an optional command line-like interface.

Additionally, you can assign specific browser actions to mouse gestures or keyboard shortcuts. Vivaldi also comes with a dizzying amount of customization options; there are over "1 million different ways to make Vivaldi your perfect browser," according to the company.

Using Google's Blink engine, Vivaldi takes up less memory than Chrome, Firefox, and Safari, and it supports most Chrome add-ons, should you want them. The only things missing at launch are synchronization and email, but the team is working on these.

There are Windows, OS X and Linux versions available, and the company is planning to bring Vivaldi to the mobile platform, too.

Vivaldi definitely isn't a browser for casual users, but that's not its main market. Head over to our download page for Vivaldi if you want to give it a try. After only a few hours using the 1.0 version, I think Vivaldi could become my browser of choice.
