I want the URL to be a hyperlink when In the SharePoint Library Settings page. It would be much nicer than copy paste all the time. Is there anyway to do this?
This is a file that's located on the server's file system. Microsoft definitely doesn't recommend changing this file for the following reasons:
Having multiple web front ends means you will have to change the page layout on each of these servers. If the different servers are using different files on their file system, different users will get different results depending on which web front end server they're connecting to.
Changes will get overwritten in SharePoint patches
My solution would be to edit the site's masterpage instead. Create a copy of your masterpage called "Seattle_customized" and add the following piece of code anywhere in either body or header tag.
Edit: I edited the listedit.aspx page and added the java function. The fix is working! I had no luck when adding to the master page so decided to take this route. I will be looking into why it is not working when added to the master page for future proofing when sharepoint updates are released.
