Prior to the redeploy the other day, pressing Tab on a line in the SEDE editor would create an indent of two spaces, and pressing Shift+Tab would un-indent by two spaces. Hitting Enter at the end of an indented line would bring you to a new line with the same level of indentation
Now, pressing Tab indents by a
\t, and pressing Shift+Tab does nothing. Hitting Enter at the end of an indented line brings you to a new line with the same level of indentation, but the tabs are replaced by four spaces (and Shift+Tab still doesn't work).
I don't really mind the change from two spaces to
\t for indentation, but the other two changes (loss of un-indentation and munging of indentation on new lines) are not great, particularly because the combination of them makes it inconvenient to un-indent on a new line (you have to backspace through multiple spaces).
