Well, to create the layouts I had to consider a lot of combinations. Some are really good like "ing" but they could compromize others. That's why I decided to made it fully customizable for the user. You can change any letters if you want!
Even Swiftkey dropped from iOs. Main reason for me to dismiss Keybee Keyboard from iOs is that for some forms (like password) you are forced to use the apple keyboard. That's a no-go for me.
