Key Rebinding Plugin w/ Controls menu included [Video]

I have recently started working on some C++ code to rebind keys at run-time in UE4, and have made some pretty good progress. This stuff I’m working on will also come with a free menu to demonstrate how the code can be used. Here is a video showing off the progress I’ve made over the last 2-3 days:

Let me know what you guys think, as I really need some input!

Edit: Question for everyone, how important is the demo menu? I really want to emphasize that the menu is meant to be a demonstration, not the core of what I will be selling.
