What does this mean "Touch Input has been detected. Do you want to enable the touch mode layout?"?

Touch Input

Hi Carla,

It means that most likely you’re working on a device like a tablet
or computer with a touch screen, so you can use your finger(s) or stylus on the screen
to control your actions in the program.
Not sure if  it  makes working with eM Client easier than with mouse and keyboard.

Try it out if you’re adventurous…
