ability to edit comments is pretty self-explanatory
expando for text posts so you can see what the text is without going to the actual post page
Comment preview
Yep. I've got editing comments in the list. The expando for text makes sense. I'm adding that.
I noticed this morning that chat doesn't work if the page has been idle, but it works fine after a refresh. No big deal but I'd thought I'd mention it. Thanks for adding the text expando to the dev pipeline!
