I'm normally a back-end developer, however I have recently started having to create front-end fixes in a React app (Native and Web). Therefore, I need to learn React (my JS is okay). Rather than complete basic projects I want to build something useful, however I haven't thought of anything over the last week.
What do you, the community, wish existed that could be built in < 3 months? I'll build the most asked for thing, whatever it is, as long as it has a substantial front-end element to it.
