Well this is cool! Using the #reMarkable, I uploaded some PDFs of fillable #dnd character sheets.
I only have the name “Cudgel” written in, but experimenting, I can add multiple layers, and then hide or show layers.
So... infinitely re-usable sheets.
Don’t know if I can copy a layer’s content, and I can’t copy pages of a PDF, so need to do a little more experimenting.
