Publisher Description:
The ultimate advance in Web browsing without an address bar

Design with purpose down to the last pixel

The designer here designed Sleipnir from scratch to provide a Web browser that can make browsing the Web for the people of today even more enjoyable and useful. As a result, we were able to place the number of advanced features such as the easy to view thumbnails that display pages and the evolved search fields that can find open pages in no time into the breathtakingly beautiful and simple toolbar. Each part of the bold looking design has a purpose.

Gestures that captivate you the moment you touch

The bothersome task of aiming for a small button with your cursor is unheard in Sleipnir. You can simply use touch gestures with Magic Mouse or the Track Pad to close tabs, go back, and more. Furthermore, because you just need to move your finger tips, bothersome keyboard operations and even just moving the cursor is not necessary. Even if you are holding a mug of coffee or resting your cheek in one hand, you can continue to browse the Web just like usual.

Quickly find open tabs even when they reach 100

Compared with the time we first embraced tabs in Web browsers, it is becoming more and more common to simultaneously open a number of pages such as Web applications and social networking. Sleipnir has been carefully designed in every nook and corner so that you can quickly find the page you want from all the rest. Whether you have 100 tabs opened or not a single tab open, you can find your desired page in no time at all.
