Where user interfaces are concerned, it’s either old school standard, or custom designed for someone‘s story. There hasn’t been any innovation on a new standard interface. The tools are there, like Vorple and fyrevm-web, but no one has done anything to date.
For what it’s worth, I added this (the pop-up common-verbs menu) because I figured that people might want the shortcut for typing on mobile devices. It wasn’t particularly intended as an introductory or IF-newbie aid.
Then again, I never did any user testing to find out why people used it. Or whether people used it.
