Nice! I like that idea. Would this be the only icon that can show in that location of the layout or are you thinking of having a variety of icons that could show in that spot? It would be handy to have an easily accessible lexicon for reference in the app menu since there is potential to have a lot of icons and meanings for them throughout the UX. Might also be good to spec this out so clients have the option to unify around this and maintain good UX. Otherwise, this will get overwhelming for newbies and normies.
