Can I change the angle back to degree increments like it used to be? D’:
The increment is now settable by the user. You can either type a number or you can change it in the header, the section for the knife tool options.
Going back to the old way would mean that people who wanted, say, a 10 degree angle, wouldn’t be able to do that while the new way allows that flexibility, as well as the flexibility to get the old increment if you like that.
