my website needs a markdown editor similar to that on stackoverflow, which you are sure to have used, very concise and powerful, currently using the WP-Markdown plug-in, which is not bad, but does not support copy and paste of images (from the clipboard), and markdown on stackoverflow uses this powerful function, as shown in the following figure

in fact, the codeshelper editor I am using is better (this is not digging the corner of sf). I have tried several markdown editors before, such as WP Editor.MD, which only support back-end editing but not front-end editing.

I don"t know if there is a similar editor that can be recommended, or for a fee, thank you!
