You can always do what I do when I can't think what to put, Steve, and go with an emoji: 😂

But you could go with one of these Brit expressions:

Smashing!

Blinding!

Sound!

That's Boss!

Quality!

Top-notch!

Cracking!

The bee's knees!

Thanks for the translation of SH! I needed that.

Oh, and THANK YOU!!
