Sorry for this newbie-stuff.
've created my first PCB and as far as I remember, upon creating the project or so, i dropped a lot of layers, that i thought i wouldn’t need.
Hence I have only F.Cu, B.Cu, F.Silkscreen, F.Mask, Edge.Cuts, margin, F.Courtyyard, B.Courtyyard and F.Fab in my appearance window layers tab. Yes I can turn them active or not and visible or not.
But how do I “re-activate” eg B.mask, so that it reappears into the layers tab?
