Joe, great post fascinating.

Here I have iphone/ ipad for 5 years or so and did not think of this or the way you laid it out, Great info.

In short: the ios i way less user friendly than normal finder system IMO.

Ok so there are no apps to find! Except what you see on your screen...

The PDF in question is a manual of a product I bought. It opens up well, and looks great, but I don't see a search bar. Is that unusual, or I'm missing it? And what it opening it up if you can guess? And one cannot open with other apps that might have search bar?
