I don't know if this was intentional or not, but I'm not able to rename sprites in the 2.0 editor, regardless of whether they were imported or not. I can rename the costumes, but not the sprite itself. Is this how it's supposed to be? If not, how can I rename them?

Thanks in advance!

You should be able to rename sprites by selecting the sprite in the sprite box, then clicking the blue “i” beside it. Then there's the text box where you can rename the sprite. c:

Oh, wow, that feature's kind of buried in there. :P
Thanks!
