I love that i can write my story in one place rather than writing it separately for each character or chapter! It's not perfect by any means but gives me time to focus more of what is important without having to stop mid-sentence (which happens often).
The font needs work - there are many fonts available which don't look professional enough so choosing was difficult at times because every choice felt wrong somehow; even though they were all good choices really!! Just be patient with yourself during this process as you learn new ways how things should appear when written out loud etc.. Also try different layouts/fonts if anything just looks too much like word otherwise its very easy once your used to using celtic words & phrases ;) Great app which helps create books quicker :).
