The service Online Text Tools has no documents, could someone please add:
Unfortunately I’m unable to crawl the documents 
.
Even if they can’t be crawled it is better to add them because then you can add points not linked to a document, but right now you can’t.
And if you add the then they will be linked on this page
The problem is that documents can only be added if crawling is successful (or doesn’t throw errors despite unsuccessful crawling). That’s how Phoenix works at the moment…
