After getting a better picture of how I want to approach the solution, I sketched-out some wireframes for some of the designs I was weighing. Considering that this is a UX challenge, I wanted to maximize interaction with my designs by coding a mockup and getting real people to use it, so I heavily annotated each of the designs to be certain I could code it in a reasonable time and that I wouldn’t waste time on a design that wouldn’t be a good solution.
I didn't render any digital mockups in Sketch because I thought pushing-pixels and selecting fonts would be a waste of time. I wanted to get going on coding as soon as possible, as the time it would've taken to make non-interactive mockups is better spent on making something people could use in a challenge like this. I coded two prototypes that blended features from a couple of my designs. From the screenshots I was given and my analysis of the problem it was apparent that there should be a split-view in the fullscreen app with one side devoted to writing and the other towards inspiration. The main difference for these versions was the best way to present the inspiration content. Version 2.1.0 featured a drop-down list to present pre-made cards as inspiration, and Version 2.2.0 featured a continuous scrolling list of past cards sorted by relatively arbitrary numbers as inspiration. Please have a look at the links to get a feel for the mockups and a sense of the usability before reading on.
