Again, I’m not awesome at modding, but I had a pretty cool idea earlier if someone wants to run with it. A portable Ark. So you can upload and download your dinos/items/whatever from wherever you happen to be. Taming a max level scorpion in a cave, but your base is all the way across the map? No problem, upload him to your portable Ark and re-download him when you get home. I guess this is mostly only useful for single player/local or unofficials that allow uploading/downloading. But I thought it cool nonetheless.
Edit: It would also solve the teleporting with your items problem in a dirty kind of way. Just upload your items to the Ark before you respawn somewhere, and download them again when you get there.
