Added Back/Forward gestures

The popular Back/Forward gestures of the Sleipnir Family has been added to Sleipnir 3 for Windows! Thank you to the many people who requested it to be added.

The Back/Forward gestures can be used by going up the screen and then either left or right.
Just like in the Mac and iOS version, go left for the Back gesture and right for the Forward gesture.
(This can be edited from: Customize > Mouse > Mouse gestures)

Please check the image below for more information about other gestures.

Mouse assignment settings

The Sleipnir 2 function function with even more requests, partial support for mouse assignments has been added!

Mouse assignments can be made from Customize > Mouse > Mouse assignments. You can customize everything how you wish, such as clicking the mouse wheel to quickly switch to full-screen mode.

We will be combining the old gestures of Sleipnir 2 with the mouse gesture assignment function so that our long-term users can start using them more easily. We are also working on developing TouchPaging further so that new users can experience the pleasant touch feeling to control their browser.
