This is my personal layout based on Hands Down Rhodium, adapted to a Hummingbird style keyboard and with Spanish Support. This layout relies on Eurkey for especial characters.
All extra layers are layer-tap under index and middle fingers, this reduces holding thumb keys as i find it uncomfortable long run.
