Until a little while ago, I haven't had much use for the rotation blocks. However, when I did start using them, I found out about the rotation center of a sprite. I think that Scratch 1.4 should include a block to control the rotation center, and I think it could eliminate the need for complicated trigonometry in some Scratch projects.
What do you think?

you can manually set it in the paint editor (bottom left)

I know, but I think it would be cool if you could reset it while a project is running. That way, projects wouldn't have to use such complicated trigonometry in some cases.

make another costume which is identical.

Still, if you wanted to change the rotation center in real time, you would have to create hundreds of costumes to be able to move the rotation center anywhere around the screen.

That wouldn't help anything...
But really, I think the need for complicated triginometry is encouraging us young kids to be advanced in math! Really what they are doing is trying to make us all geniuses!

Yeah, apparently everyone agrees. Oh well, I guess that destroys my hopes of making a "3-D" game before 8th grade . . .

Don't worry, you can learn trigonometry online. We're in 8th grade and have only learned the basics (not even sin, cosine, and tangent have been taught yet). You can learn it at a forum topic on Scratch itself - just look for a post by Archmage near the middle of the first page:
