Description

Jira task: https://jira.corp.adobe.com/browse/SITES-22608

The extension is to add the rail.

Features

Hey @ahajji87 this is a public repo. Let's only reference publicly accessible resources. At the moment this is only true about the content of the PR description.

I didn't find a way to preview the draft so probably users will have hard times with it too

You can review the draft by clicking on it. On the list, we see a part of it, and after clicking on it, we see the entire draft. I will add it to the text.

Please, check the new changes, now we can edit the drafts and we show by default 3 drafts with a (show all) option
