I would like to take a shot at this in a day or two.

I figured I would take this time to reach out to you as well. I am currently building a plugin with RageNativeUI and I would like to figure out a way how to make a text box either within the menu or a pop-up text box for users to input a string but I for the life of me cannot find any resources that would help me achieve this... do you have any suggestions?

@petergeorgas check out some of the classes I've made for my LiveLights plugin which extend UIMenuItem to create a pop up for string (or other data type) entry: https://github.com/pnwparksfan/rph-live-lights/blob/master/LiveLights/Utils/MenuItems.cs
