Mark-up only view
Logos for Android is almost there for me.
Only two features stand in the way between the "very-good" rating I currently give Logos and the "out-of-this-world" rating I have rarely ever given anything outside the Word to.
1. Line-by-line scrolling, as currently featured on iPad. We've know this is coming, very soon hopefully.
2. Easily toggled view mode to take advantage of notes and markups. Particularly the ability to display only those parts of the open resource that have mark-ups (notes, highlights/etc.), perhaps directly from the menu button, but definitely not requiring more than one navigation click/swipe/press/etc.. I don't even think the Logos iPad app does that yet. In fact, I don't know any mobile reader that does so. Lets take some leadership here and make Android the first with this.
