Feature Request: set `preview` as default mode

[gudh]

Hi,

is it possible to set preview as default mode for the editor?

Because sometimes, users just want to preview the content instead of edit it

Thanks!

By the way, is is possible to set "Table of Content" view to true by default when previewing?
