question?

so whenever we're running portrait enabled apps (ie. conversations), and are about to write something (which by default will pop the virtual keyboard and ruining the orientation back to landscape), will installing this will make it run the portrait keyboard instead?
but still preserve the original virtual keyboard on landscape orientation?

not that i don't like vertsms, fastsms or other similar apps. but i wish to keep using the original as much as i can
so this could be the remedy
