This is really niche, and I'm not sure if this will be implementable. But if possible, will make password autofilling smoother. I'm using a 2020 intel macbook pro.
To fill passwords. I click the username field, it shows me some suggestions, and I can put my finger on the touch id to instantly fill it.
I click the username field, it shows me some suggestions, I press enter to select first option and then I can put my finger on the touch id to fill it.
The difference is only in Orion I have to explicitly press enter, which is 1 extra keystroke. In safari it implicitly detects if I try to use touch ID. I can add pictures later if my description is not clear.
