Two new ‘mini-extensions’ are available on the Extension Gallery:

Classic Customize Redirector: Don’t like the new Customize page? Enable this to get the old customize page again.

New Lines on Ask Boxes: Enables to 'press enter’ on ask boxes. Useful if you message with people a lot.

Click on the X icon on top of your dashboard, and then Get Extensions to download them.

Also, XPreview has been updates to fix a couple of bugs. If you have Automatic Updates on, you should be updated to XPreview Version 1.0 Rev C by now. =3

Again, thanks for using XKit.
