Those of you who missed GitHub flavoured Markdown support, and code highlighting can log into http://beta.checkvist.com
and see how it works.
Another thing to try are changes in multi-line text editing. Now when you edit a multi-line text, Enter starts a new line, and Ctrl (or Meta) Enter submits the text. On one-line list items, Enter works as Submit.
As usual, we'll be glad to hear about the bugs and glitches. If anything looks or behaves ugly, we'll fix it. The main server update is planned for the end of the week (hopefully).
