If I could ask for one thing in this game... it's this - I'm certain it can't be that difficult to add, but if only blank runes could be stackable, it would save me so much time and patience, as I make and copy marked runebooks and atlases on a very regular basis.
If you'll change the poll question to a simple "Would you like to see blank runes stackable?" then I'll vote. You won't get as many No votes that way.
It would be nice for them to be stackable. My current way of dealing with it is that I just mark a whole bunch in my house and throw them in an empty runebook. Remove and remark as needed.
I voted yes (tho I really would not sacrifice one let alone two feet!), but I would like to reluctantly point out that even simple changes to old OLD code has a tendency to be... problematic. I think it would be easier (and less risky) to create a new kind of rune, with a new code, and heck even a new runebook to put them in if needed. It would be redundant, but probably a lot more likely to make this wish a reality.
Or if your runic atlas has available charges, add a "create rune" button.
