I understand the move for choosing R5 with the results of the poll, but I also think that it's close enough that a seperate kit adding R4 bottom row would comfortably hit MOQ.
I also understand the suggestion of simply getting the bottom row from another set, but Griseann is different from most other sets by the inclusion the coloured legends on the bottom row, combining with another set will lose a part of what 'makes' Griseann, well, Griseann... I wonder whether just including the pad printed R4 keys in one of the extension kits, leaving us to gather the rest of the R4 keys ourselves, could be a good compromise? I almost exclusively use my thumbs for the bottom row keys which makes R5 highly uncomfortable T_T
