Woah. Thank you for taking the time to do all of this! I know tiled can be a bit difficult to get into. Every time I revisit it I end up bit confused and having to relearn it a little. I also keep meaning to update the original sheet with my takes on assets people have made and getting permission from them to put them into the initial set, but life gets in the way sometimes.
I appreciate all the ideas for new assets to sit ontop of stuff too, that's great and maybe easier for me to dig into than whole new tiles for all those things. When things smooth out and I get a chance I'd love to add them!
Be sure to share the things you make after putting all this hard work into organizing it all! <3
