Great that people are developing tools but personally I use OpenRGB as its broader focused than just one manufacturer. It also uses the same underlying OpenRazer drivers for Razer devices as well as supporting other other RGB devices.
RazerGenie seems a little too focused to me but maybe there are benefits of such a tool I’m missing?
Also English language books are going to be predominantly sold in English speaking countries. And it makes sense cost wise to target both markets together rather than printing individual runs priced for individual countries where possible.
And Canada and the US both use dollars; there is potential ambiguity in price for manufacturers and retailers, so better to clearly specify both. There is not ambiguity with the peso - if a customer sees a book is $10 they will know there is a different price in pesos.
