In one of the alphas, there was the feature that I could long press the keys and the underlying punctuation sign would appear (if there is no umlaut behind). This is not possible anymore in the current version but was very convenient once you learned the positions. Especially for apostrophe in English. Is there a way to make this feature available again?
Quick Numbers & Special Characters Access
Out of my own perspective it's slow to type numbers and the alphanumeric characters because accessing them takes a lot of time and it's boring. So to fix this kindly add numbers and those alphanumeric characters on letters such that when I long press a letter I can easily access the alphanumeric characters or numbers, like other keyboards. Also add word/emoji suggestions on top of the keyboard meaning you guys have to resize the keyboard to a smaller size (please do that). And your word correction is not helpful to be truthful i.e.on Android. Borrow some ideas/features from SwiftKey keyboard. And honestly change UI of the menu, give it some material design it's horrible.
