The popup when you load a custom item does tell you how: To permanently save it, click on the icon in the Spawn menu. They're not saved automatically not to clutter your items, this way you only save the items you want.
It only captures a single item. Any more would require it to essentially temporarily save a custom item inside it, which just gets really really complex and won't be happening.
Can you make a favorite button for levels that people create, and when you want to play them there is a bar with the level name on it, you click it an it loads the level.
When i said if you can make the ragdolls have the ability to hold each other, i didn't mean they will automaticly do it, i meant that when you press f on a ragdoll's hand it can hold a another ragdoll

I would refresh the game in a fresh browser with no tabs. Sometimes the WebGL downloading process gets confused. Thanks for checking us out!
