First a possible bug... when I view a commentary on Android and wipe down to bring the input box which has the current Book + Chapter + Verse, sometimes when I am reading a commentary it does not display this but simply displays the page number of the commentary. It seems that when I start out at a book,chapter,verse in the commentary all is well for at least three or four page turns, but after that, only the page number is displayed in the input box...
Second, a suggestion... in the same input box there is an extra white space after the verse so I have to press the backspace/delete key more than necessary. This is trivial but an improvement nonetheless.
