Tabs that make full use of the screen arranged on any side or in multiple rows

Tabs that make full use of the screen arranged on any side or in multiple rows
Pursuing an ideal tab browser, we have succeeded in creating customizability and ease-of-use that can not be achieved by just extensions alone.

Styling of tabs can be selected as compact single-line view and easy-to-view multi-line view, and tab sizing and positioning can also be customized, making it possible to create the perfect layout for your laptop, wide-screen monitor or whatever screen you use.
Furthermore, with the tab group function that prevents the confusion with many tabs, or the newly added "Smart Tab", adding, positioning and deletion of tabs is determined based on relationship with previous and next tabs.
Please try out the innovative Sleipnir-like clever tab functions.

150 functions within a 5cm motion of the mouse

Back, refresh, close, and even search functions can be done with the mouse alone.

A flick of the wrist to perform mouse gestures that execute countless functions, SuperDrag Extension, and the newly added "Pickup Search" can be executed by keyboard searching or by simply drag and dropping.
This is the results of all the trial and error conducted by us and the users of Sleipnir.
Please try out the easy to use mouse operations made possible by the countless feedback of our users.

A Web browser that will move like magic even after a month of heavy usage

You won't need to restart again even with YouTube or Twitter constantly open.

By implementing a new rendering engine, not only have we improved security and basic performance such as page rendering speed, but also vastly improved stability after long-term usage.
So, you can keep comfortably using video sites such as YouTube, and popular JavaScript heavy sites such as Gmail and Twitter.
(In addition to using the default WebKit engine, you can instantly switch to the Internet Explorer engine whenever you wish)
