As someone new to the Mobx paradigm,

I would greatly benefit of a quick rundown of the structure of the application when regarding the Mobx framework specifically (so the src folder). Many of the Mobx 'example' applications I have found online use different variations so it can be a little difficult to deduce the goal of parts of the structure.

I am thinking a blurb about any specific variations you chose and why you prefer this structure for your Mobx projects

This looks great!
