Thumb-Key installed on a relative's 'phone. I didn't enable anything fancy, or enable the #MessageEase compatibility layouts. But I was explicitly asked to install Spanish and French alongside English. I made the relative make the layout switching gesture multiple times, so that it stuck. Otherwise I knew what the first panicked 'phone call would be. First panicked 'phone call: all of the letters have disappeared from the keyboard. There is a setting in the Thumb-Key settings called "Hide letters", and it had been switched on. https://f-droid.org/en/packages/com.dessalines.thumbkey/ There's another option called 'show toast' and is a prime example of programmers writing for programmers instead of for users. 'toast' is specialized Android developer jargon. Users won't know that it means showing the layout names for a brief period when one switches layouts. They'll be wondering what the Hell bread has to do with a keyboard. #ThumbKey #Android #SoftwareDevelopment #ComputerProgramming
