Expanded Two Finger Gesture Functionality

Description of feature request:
I love BTT and use it constantly. I could be more productive if I could use two and three finger gestures more. Using four fingers is bulky, and frankly don't work well with my fat fingers on a Magic Mouse.

I would like to see keeping one finger still while one finger slides left and right. This gesture is similar to the TipSwipeLeftFingerUp, except it would be TipSwipeLeftFingerRight and TipSwipeLeftFingerLeft.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Trackpad and Magic Mouse

Additional information (e.g. related issues, screenshots, workarounds, etc.):

Thank you so much for an awesome product and the continued support and effort.
