Thanks! It's a nice QOL feature I added to BFNSU, and it would be a good addition to your unofficial BFNS updates as well.
As for sharing how I make my textures, I'll probably release a video on my YT channel at some point showing how I do it, for anyone who is interested. Also, I have an ideas document where fans can submit ideas for BFNSU. If you have any ideas, please make sure to request editor access here.
