I would love to be able to change profiles on the OnlyKey Classic, I use more than 12 slots for work and I don’t love having to have two different pins to use multiple layers of the device, I do like the implementation of it on the OnlyKey Duo. In my opinion, with the form factor of the Classic, it would be nice to choose what button changes your profile and how long it needs to be held to do so.
That is all, overall, the product works great, just a minor quality of life update would be hugely appreciated!
