I miss the “swipe to punctuation” from Swype. Typically, “w-e-.-l-l” to prompt “we’ll” instead of “well”. The other thing is the long press option on the main keyboard only has one alternate character. The secondary keyboard has more. I like it, use it as my daily driver & I’d recommend it.

Wow, that’s a big 3d printer! (If you’ve ever printed spaghetti on a smaller 3d printer then you know)
