Today I saw an $odd$ $looking$ italicised word in a question title. It turned out that the OP was using double dollars as opposed to the usual stars. So I edited their title. In doing so I discovered three things. Firstly, and I presume that this is by design, the usual Markdown (I think that is the correct word...) stuff doesn't work in the title. Secondly, there is no title preview. And thirdly, rolling back your own edit almost-instantaneously doesn't just ignore the edit, it counts as two edits.
My question is this:
Can something be done about previewing titles? Why is there a preview to the body of the post, but not to the actual title?
(Perhaps I am just missing something?)
