If memory serves me correct there was an easier way to return the objects to the horizontal by using a couple of keyboard presses, but for the life of me I cannot remember them.
Works if your close to horizontal or vertical. If guess you can move it close before using.
I was unaware that it doesn’t require you to convert to path first.
Seems like an odd place to put an align tool.
User interface work is cumbersome, and since we don’t have a way to select just a line in LightBurn, an “align” tool would need to be a mode that you turned on, like Line mode, so you could then click on a line to align it. Since all of that “plumbing” was already in place in the Node Edit tool, it was put there for now until we figure out a better place for it and do all the remaining work to make it its own thing.
This way you get it now and can use it right away, instead of having to wait for the rest of that work.
