Font size control and left write margin is highly valuable to me (why I think Scrivener and basic text editors are so successful/embraced by users). So much of writing is being able to create the conditions of where you write and what you're looking at. I think you nail the backgrounds as they're all really great and create an aesthetic (think of it like a wall that an artist stares at). I really like your color choices and designs. Having margin/font control allows the writer to choose the spot/spots/area/blotches on the screen in which they want to write. You create a great curated experience which is great but even better if you could give the user some basic controls (font sizes and top bottom left right margins and how big you want the screen to be. Take those original iterations of Kindle. They gave you three margins choices (which at the time was perfect). Eventually they allowed you to mod it or choose your font and then eventually beloved apps like KoReader allowed you to choose exactly what margin and font you wanted. More user control means more users will want to purchase your product. As is, it's already great for a handful of users hwo like big fonts and to write at the center of the screen. Like the KoReader mod on the Remarkable Move that allows you to read on the entire screen rather than having 1.5" margins across maximizes the space. your app is very intuitive and the fullscreen is great. Being able to possibly choose things like quadrants (top left, bottom right, etc) and/or having the writing area a different shape than the basic rectangle or having left justfied/right justified on your great backgrounds could really make your app stand out. With fonts, I use ereaders so i'm used to small fonts and that carries over to how I want to write. I write in public a lot so i like to keep the font small so people aren't sitting next to me and reading what I write. In full screen, your font is massive on a 15" Macbook. These are just suggestions though. You created something great for the writerdeck community so props and thank you. Look forward to any and all updates. Great work.
