Please can we display the anchors when printing? (I mean the actual command-P, to a printer, kind of printing)
That sounds like a reasonable suggestion. I would make it controllable by the “Show Nodes” checkbox? Or would you need a dedicated setting?
I’d prefer a separate setting but either way is fine with me.
And do you need that in the grid and/or in the text output?
And do you need the anchor names?
I just need them displayed in the grid. Names not important. But hey, while it’s nice that you’re writing this software just for me, we should probably think about what other users might want too. 
Yes, optionally including anchor names would also be useful.
I always wanted something like this. Could it be possible to have an option to save as pdf with anchors on?
