For me, the refreshtime of the preview (I split my view, so I can see both, code and preview at the same time) the refresh time is a bit to slow. I would like to change this, not each would like to have a faster or slower refreshtime so I think an option to set the refresh time would be very nice. For chrome there is an Markdown extension too, this has no delay time "type smth -> instant reload".
