Why do we have to "import to writer" from Zoho docs?

It seems like Zoho docs and Writer could be more integrated than they are. It took me forever to figure out that you have to import a document specifically to Zoho writer, and that the document won't show up in the "open" feature in Zoho writer until you do so. You'd think that the folders in Zoho writer would correspond with the folders in Docs. That certainly seems to be the intuitive thing. I was quite surprised to find out that this was not the case, and am still somewhat confused about the degree of integration between Writer and Docs.
