Ability to choose single or split screen in Verse mobile

Split screen for viewing Verse emails is too narrow for most tablets (list of emails on left, email view on right). Phone view has one screen for the list of email, then reading an email also fills the screen, much better for most mobile devices. However, split screen is currently triggered by screen resolution and can't be changed. With modern tablets having greater screen resolution (eg, my Samsung Tab S4), this is an increasing problem, that split screen is the default chosen, with the result of much too narrow/small columns for mail. My idea is to introduce the ability to choose whether to have split screen or phone view (single screen). This choice could be part of settings for mobile Verse.
