@davidfor - the 'hangup' I have with the additional functionality being tacked onto the Open With PI is that it 'prolongs' the life of the PI, which, IMO at least, has for all intents and purposes been replaced with the recently added built in Open with functionality.
I uninstalled the PI and its json and html files as soon as I could. Primarily so I didn't have
Open With and
Open with sections in Preferences->Keyboard. I would think new users (even existing ones) could get easily get confused between the two - this is not the PI.
I'll leave it at that.
