Change comma position
On the key for the comma (,), there is also the period (.), colon (:) and semi-colon (:).
I can type the periods without any problem, but when I want a comma, I almost inevitably end up with colons or semi-colons. I often have to revert to the normal keyboard on the Android phone to type the comma, before I can continue writing the message on the WRIO keyboard.
Since commas are more common than colons or semi-colons, wouldn't it be better to e.g. change the configuration so that a 'long press' or an 'upward swipe' would give a comma instead of a colon or semi-colon as is the case now?
