The “Cancel” and “Ok” buttons should not be part of the keyboard. The cancel is problematic in that it is too easy to hit when wanting numbers as it is in the location of the numbers shift on iPads.
Also, for consistency, ok should be Apply.
not everything has to be the same like on an ipad
Ok, not everything has to be same but consider this. I am replying to you on an iPad. My fingers know where to find things.
After typing cancel 3 times over the past two days when I was looking for a number and then havin* to start over… this is not productive and easily improved.
and I’m always confused with the keyboard emulation on the ipad, coming from Android devices
On every session i had with the sq i was hitting the cancel button accidentally at least one time. Hate it.
… you are not the only one with this problem 
I would like more special characters (ä,ö,ü,ß) a well. There would be space in the numbers section + caps lock.
and for the friends of user-colors you could add more colors like orange, purple and darker green to the keyboard
