Fn key support is a bigger deal than it sounds. A lot of Citrix and RDP users have very limited hotkey availability since so many standard combos get intercepted by the remote session. Fn combinations are one of the few that usually pass through cleanly.

One thing worth adding down the road: a fallback to keystroke simulation for VDI environments where clipboard paste gets blocked. We built that into DictaFlow after a bunch of enterprise users hit that wall and it opened up a whole segment we did not expect.
