Your line of questioning is based on an incorrect set of assumptions.
The number of clicks is an implementation detail. It depends on whether or not you're using the web file API, some browser download capability, a browser plug-in, a mobile app, desktop app, a webdav server, or something else.
For people trying it for the first time, they often have the experience you're describing. But for most anybody that actually picks this up and uses it on a day-to-day basis, they use something else that saves transparently and automatically.
All of this is orthogonal to whether or not it's in a single HTML file. I fear you took lelandbatey's original ctrl-s reference a bit more literally than intended, though if you want to be pedantic, I can confirm I use applications in this style all day as part of my daily workflow and I do press ctrl-s and it saves with no further interaction in fully patched versions of Chrome, Firefox, and Safari with no plugins whatsoever.
Would you be so kind to share how you manage to get them to save without further interaction? That would really add usability. Maybe I did take the ctrl+s too literally, but being pedantic was not my intention. Merely hinting at this usability issue. So a solution would be very welcome.
(And I am not the one downvoting you, in fact I couldn't even.)
As an aside: I do find these applications very interesting and am considering to make use of Nullboard myself, but also am weighing it against simply using org mode in Emacs and am looking for any advantage it might offer. Of course the ctrl+s issue plays a role there as well.
