This is just a philosophical thread (and thense meriting the 'back' key!).
I've various frustrations with the iOS/iPhone version of Logos. The issue, however, is that other mobile versions are presumably not as advanced as the iOS one and so I wonder if iOS improvements maybe need to be 'sometime in the future'.
1. I use iOS primarily for reading; I 'download' books and then proceed to read them, typically several at a time (they're boring). The problem is that you have to turn off the iPod/iPhone's internet in order to find your downloaded books. I thought of using Favorites but that's also a pain, since it doesn't show the titles. In Library, you only have 'Recent' to work with but any random book open brings 'Recent' to the top.
2. That leads to the missing titles. Instead of titles, it uses abbreviations. I opened a second panel, while I was reading MPAT (if I remember right, aramaic texts). That brought up PPANET with a whole bunch of squigglies. PPANET? No hint of it on my Logos5. I also searched Logos.com. No PPANET to be found, though it's related to 'Late Babylonian Chronographic Text'. Turns out, it's another book I'm reading (!) but not the english version. Go figure.
3. That led to the next problem. Clicking on the Contents button while off-line (in order to find the downloaded books!), leads iOS Logos into never-never land. Apparently it doesn't know PPANET's not loaded nor that the WIFI is turned off (to see the library of course).
Now, I put this in the 'philosophical' world because I really think the mobile versions (iOS included) are the wave of the future relative to large libraries (Logos' primary claim to fame). The portability relative to the massive library (massive for me!) is 'the future'. But the iOS version (don't know about the others) doesn't yet really work well with large libraries.
I know it's going there ... just some curiousities like PPANET!
