Affinity is starting to take shape better and better.
I would also suggest introducing a bird icon in the place where the beams meet the guides.
By right-clicking a pop-up menu pops up and shows the units in which the project can be.
I know that in Mac the current unit is checked, while in Windows this check mark is not displayed.
These stamps appear, for example, in the top menu.
So add that and Affinity keeps getting better and better for the job.
