I hope TRMNL will start supporting 6 color e-paper displays more widely. I have one of these 6 color panels running with my own custom firmware on their BYOD license and I'm really happy with it, just wish it could take advantage of the color capabilities.
Yes! I'm in the same boat! My guess is that there's something in the backend (image cache/storage size) that presents as a cost/logistical problem instead of as a technical one.
