This is not a list of features but rather a list of hidden features that are not well-known and commonly suggested. This will be useful since people don't know that the feature exists, and it also can lead them to use a new feature. Workarounds will not be on the list, as the Scratch Workaround Guide already exists.

There will be only commonly suggested but already added or highly unknown features. This will not link to any suggestions or anything. This can also be useful for QaS if some people don't know the feature exists. I don't know who will manage it, though.
What do you think?

Example

Restoring sprites/audio/costume
You can restore a sprite by clicking the “edit” button in the editor and then clicking “restore” this will only restore the last sprite that was deleted; if you leave the editor and come back, the deleted asset will be gone.

If it included funky block workarounds (like the one for previous costume where you make a costume called that and delete it) that don’t use other block but instead a quirk of the way it works

Nobody, not even ScratchCat, has been in Scratch for 20 years.
