Just updated to 1.9 today - there are a ton of great improvements there!! :) I love the new clickable titles, and how the "Deactivate | Edit | Export | Delete" row only shows on hover.
One new thing which just occurred to me is this: I think it's a bit too easy to click the "Save Changes" button when creating a new snippet, rather than the "Save Changes & Activate" button. This results in the snippet being created but not activated. I've done this a few times already - just clicked the "Save Changes" button, and been completely oblivious to the fact that my new snippet was not actually active!
It's because the "Save Changes" button is in the default location the left and is also in blue, while the other button is in white and not so noticeable.
I myself would prefer to switch these two buttons around - have the "Activate" button as the one on the left, in blue, and the other one on the right in white. I would imagine it's more common for people to want to save AND activate a new snippet at the same time - right? Or do you feel that most people would normally just create a new snippet but not want to activate it? What do you think?
My only other thought now is to maybe make the deactivated snippets a little more distinctive on the Manage page - currently the background of a deactivated snippet is a slightly different shade of grey but it's hard to see the difference unless you really look close - although I know this is also how deactivated plugins look on the Plugins page! :) Not sure what's best to do there. But that's just my impression, that it's hard to see that any are deactivated due to the background colour being almost identical. :)
Thanks for all the improvements!!
