Ok, so the Google Apps LTI is a fantabulous replacement for the old Google integration. Love it, love it, love it.
But… I find that I periodically want to be able to link to a folder of images or files in Google Drive, rather than to a specific file. But the LTI only provides the capability in the interface to link to a single file. I could, of course, go over to Google Drive, get the link to that particular folder, and then paste it in as a hyperlink, but this would seem to defeat the purpose of an integration!
One caveat: I can see where a folder link would be problematic (e.g. in when choosing a file for a templated assignment), but I'll bet that could be addressed constructively!
