Ok New update just posted, version 31 should be available in the next couple of hours. I tackled the Swipe navigation. There is a bottom bar on the listview which will allow you to use swipe gestures. Check it out, let me know your thoughts.OK very provisionally and I'll try to take a longer look when I have more time.
Your "Characteristics" feature is interesting and I guess could be refined and or added to although I guess there is a huge amount of work putting that together.
Other than that, for the moment, I'm afraid I'm negative (although I hope offering as constructive criticism).
I'm not finding the app intuitive at the moment but that may be due to a combination of me trying to give some quick feedback and having some sort of fixed plan with my own dabbling as to how I'm thinking an app should work. I'll know more with a longer play with the app.
It would be nice if you could move from chapter to chapter by a gesture (my attempt uses swipe left/right) or arrows rather than (as far as I can see) having to scroll up and select the next chapter.
The search does not seem to be working correctly for me (using Samsung Galaxy Ace 2 /GT-18160 running Android 4.1.2) in that I can not see the characters I type in. I can sometimes see the word suggestions but no text at the top.
The app has crashed once on me. I've not managed to replicate it to give some idea as to what actions I took to cause it but I have submitted a crash report for you.
Anyway, sorry the way this initial report has gone. I do wish you well with the app.
Added a few other features...
Side bar with quick list and category searches.
Long press on categories or tags for additional options.
Feedback welcomed... share with friends church and loved ones. Thanks
