Is there anyway to preview text documents as text in the preview tab. I want to be able to preview a text document and then copy the text to paste into notepad or some other application.
You've got several options now:
1- http://wiki.openkm.com/index.php/Zoho ( actual live edit integration )
2- convert document as pdf and copy from there
3- We've planned in our roadmap google docs integration, but I've yet not got time for doing it. I want to introduce this feature in next 6.0 version that really will be released in few weeks ( initally will not get it, but I'll work to be done during this year sure ).
