There are some places where words look better if they are capitalized, IMO. I have pointed those out in this screencast, these are from the top of my head. https://www.useloom.com/share/828cc3598a384178b9397cfea027125a
Vue filter like capitalize, lower could be created so the view can be updated with a simple {{ string | capitalize }}.
And could also make the code cleaner in places where .toLowerCase() is used. After this task, the code would look like {{ string | lower }} which I think conveys the intention rather well in a general manner without being too technical about it.
