[FEATURE REQUEST] preview links for drafts

[rolandixor]

Is your feature request related to a problem? Please describe.
There's no way to preview posts in the live site, only in the editor. This means for instance, there's no way to test custom CSS. Currently the only option is to publish and hope for the best. It also means there's no way to allow others within your team to see the post before it goes live.

Describe the solution you'd like
A preview link would be useful - not published among the posts can be accessed from the home page, but linkable from within the editor.

Describe alternatives you've considered
I don't think an alternative is needed here

Additional context
N/A

It shouldn't be too hard to implement this. I'll take a look at it and see if I can get something working this week.

The preview we can only limit it to new post/draft only. Example adding /preview in the end of it.

That would be perfect. Published posts don't need a preview since they're already live on the site.
