The light switch in upper left corner. Cool. Thanks!Ah, okay. That's been there since before the upgrade. I put it in to limit the quote pyramids to 2-deep. I'll remove the limits if it's too restrictive.
To remove quote blocks manually, toggle the light switch to turn off formatting so you can see the BBcode. It's much easier to change that way. That is new, the quotes appearing pre-formatted in the edit pane, and I agree, not a fan.
