Feature Request: Arbitrary angled guide lines
Operating System: Xubuntu 22.04.1
Description of the feature
There is a 16 year old request (#194) for something like this, but it is now lost in the mists of time.
When you have Snap to Guides selected, you can do interesting things like clone in a vertical or horizontal direction with the clone point aligned with a guide and then being sure that the brush will snap to the guide at other points for perfectly aligned cloning. However, not everything is orthogonal. It would be great to be able to define an arbitrary guide line using a 2-point rubberband (like the measure tool) and then have tools snap to that new guide line.
Use cases
This would be useful in all sorts of situation such as cloning parts of a building where a wall edge is angled on the frame. There are untold cases like this.
