I’m honestly delighted by that offer. But no, thank you, and there’s no need. I simply and sincerely enjoy sharing my wonder for UE4 and game development with others — especially grateful and interested folks like yourself.
Besides, I’ve already had plenty of caffeine today. Any more might be physiologically detrimental. 
Another reason I like helping out: the answer I created above turned out, unexpectedly, to be an improvement on a technique I used a while back for a very similar UI feature. So, by helping you, I also helped myself, because now I have a much better solution for this idea than I did previously, if I ever need to implement it again. So yeah, bonus.
Anyway, I hope what I’ve posted so far makes sense and it proves useful to you. Of course, if it’s not, or if it could use some more explanation, I’m happy to continue discussing it.
