Infinite Clones
Scratch limits a project to 300 clones at once. This option removes that cap so you can create as many clones as you like. Enable it in the editor settings, or set an explicit maximum with the clones URL parameter (clones=1000).
caution
Some projects rely on Scratch refusing to create more clones past the limit. Those projects can misbehave when the limit is removed. Creating a very large number of clones can also slow a project down or exhaust memory.
