All of the vector programs I use have a sort of snap to feature when rotating an object or an option to hold shift to enable this. In Lightburn if I have a shape and need to rotate it say 45, 90 or 180 degrees it’s very hard to get it to land on that exact amount (unless I am missing something). Most programs will sort of stick to those common angles until you push past them to allow precise alignment of objects.
Some other programs allow it if you hold down the shift key while rotating. I would be happy with either method myself I just find it keeps bouncing between say 179-182 rather than easily hitting 180.
If these is a key or setting for this already please enlighten me.
