How can I enable swipe typing and autocorrect in Juice SSH?

The Juice SSH app disables swipe typing and autocorrect on the keyboard by default. How can I switch these features back on? The Juice SSH FAQ says to swipe right on the keyboard[1] : > In normal JuiceSSH operation autocomplete, autocorrect and swipe typing are disabled. If you want to enter text with these features enabled, you can do so by swiping right on our popup keyboard. When done, just swipe it back to switch back into command input mode. Elsewhere, they say to swipe left[2] : > Because it interferes with typing in commands. But swipe left on the popup keyboard it will go into autocomplete/autocorrect mode. However, neither swiping right nor left does anything with the keyboard, neither within Juice SSH nor within any other app.
